Three people is a lovely number for a group costume: big enough to tell a story, small enough that everyone actually agrees on it. The hard part is getting three different wardrobes, budgets and comfort levels to look like one idea. What I've found works is one shared anchor, such as a color palette, a silhouette or a prop that connects the three, while each person keeps a clear role of their own. Below are forty trios: cartoon and film characters, food pairings, classic Halloween creatures, simple DIY ideas and bright color-coded groups. Each one covers the clothes, hair, makeup, accessories and shoes you can stand in. Open the group chat, hand out the roles and start pulling pieces from your closets.

Dividing the Roles So Nobody Gets Stuck
Most trios fall apart over who gets which role, not over the costume itself. Before anyone buys a thing, I'd sort out three questions together.
- Who hates wigs, heavy makeup or anything bulky? Give that person the simplest role. In nearly every trio here, one character is mostly clothing, such as Shaggy, Luigi or the present-day person in past, present and future.
- Who has the biggest crafting budget or the most free evenings? They take the role with a foam panel, wings or a headpiece to build.
- What is the one shared detail? Agree on a color, a fabric or an accessory everyone will wear, then send a photo of it to the group chat so nobody guesses.
It also helps if one person owns the shared prop, like the traffic-light frame or the picnic basket, so it actually turns up on the night. And plan for the weather together: if one person is in a sleeveless dress and the other two are in hoodies, the group photo shows it.
1. Powerpuff Girls Trio Costume

Blossom, Bubbles and Buttercup are a bright trio that's easy to read and easy to adapt. Each person wears a short dress or a top-and-skirt set in pink, blue or green, with a wide black belt or ribbon at the waist, white knee socks and black Mary Janes. The hair does most of the identifying: Blossom's long red wig and big red bow, Bubbles' blonde pigtails, Buttercup's short black bob. I'd put the bow on a clip rather than tying it into the wig, so it stays upright all night. Eyeshadow in each person's color, rosy cheeks and gloss keep the makeup playful. Heart-shaped bags beat fussy props, and black cardigans add warmth without hiding the color blocks.
2. Sanderson Sisters Trio Costume

The Sanderson sisters give three friends a dramatic witch costume that isn't frightening. Winifred wears a green velvet-style dress, a purple cape, a curly red wig and soft red lipstick. Sarah takes a plum or burgundy dress, long blonde waves, smoky purple shadow and a light spellbook. Mary wears a rust-and-red layered dress, dark curly hair swept up and rosy makeup. Striped tights and flat lace-up ankle boots go on all three. Brooches, velvet ribbons and small brooms made from painted dowels and raffia finish them. Real velvet is heavy and hot in a crowded room, so I usually pick stretch velvet or velour and cut the capes short so nobody steps on a hem.
3. Harry Potter Trio Costume

Harry, Hermione and Ron suit friends who already own school-uniform basics. Everyone needs a white button-down, gray sweater, dark trousers or a pleated skirt, a striped tie and a black robe. Harry adds round glasses, messy dark hair and a small lightning scar drawn on with brow pencil. Hermione's hair should be long, brown and a little crimped, with natural makeup, and Ron gets a tousled red wig and a knitted scarf. Books, handwritten timetables or homemade cardboard wands make light props. The tie in each person's house colors is the detail I'd spend on, since it's what reads in a photo. Loafers or lace-ups, warm tights and sweater vests take it outdoors.
4. Mario Luigi And Peach Trio Costume

Mario, Luigi and Princess Peach give three people very different roles inside one colorful game. Mario wears blue overalls, a red long-sleeve shirt, white gloves, a red cap and brown work boots; Luigi repeats it in green. Washable brown makeup or brow pencil gives both of them neat mustaches. Peach wears a full pink dress or a pink top with a long tulle skirt, white gloves, a blonde wig, pink flats, a light gold crown and a blue pendant. Cardboard stars, mushrooms or gold coins are fun props. I'd cut the M and L for the caps from white felt and sew them, because iron-on letters often lift on the curved front of a cap.
5. Woody Buzz And Jessie Trio Costume

Woody, Buzz Lightyear and Jessie mix a western with outer space. Woody needs jeans, a yellow plaid shirt, a cow-print vest, a red neckerchief, brown boots and a tan cowboy hat. Buzz wears white joggers and a white zip-up jacket with green and purple felt panels, white sneakers and a soft fabric hood. Jessie wears jeans or denim shorts over opaque tights, a white western shirt with yellow details, a red braid, cow-print accents and brown boots. Fresh natural makeup with rosy cheeks suits all three. Buzz is the one to plan longest; I cut the felt panels from paper templates first, since the chest panel is what makes him read and it's easy to get the proportions wrong.
6. Scooby Shaggy And Velma Trio Costume

Scooby-Doo, Shaggy and Velma are comfortable enough for a long night of trick-or-treating. Scooby wears a brown sweatsuit, floppy felt ears, a long fabric tail, brown sneakers and a blue collar with a homemade diamond tag, plus a painted black nose and a few brown spots. Shaggy needs a loose green T-shirt, brown trousers, shaggy light-brown hair and plain sneakers. Velma takes an orange turtleneck, a red pleated skirt, orange knee socks, red shoes, a brown bob wig and square glasses. Magnifying glasses, notebooks and a box made up as giant snacks round it out. The orange turtleneck is the piece people struggle to find, so I'd start that search early or dye a white one.
7. Alvin And The Chipmunks Trio Costume

Alvin, Simon and Theodore come together with oversized hoodies in three colors. Alvin wears red with a large yellow felt A, black trousers and red sneakers. Simon wears blue with round glasses, dark trousers and blue shoes. Theodore wears green with khaki trousers and green sneakers. Brown ear headbands and small fabric tails go on everyone. Hair can stay natural or go under short brown wigs. A little brown shadow, rosy cheeks and a tiny painted nose give an animated face without covering it. I'd size the hoodies up so the sleeves hang over the hands, which is how the three look in the cartoon. Toy microphones or cardboard music notes help the singing theme in photos.
8. Three Blind Mice Trio Costume

The Three Blind Mice cost almost nothing if your closets already hold gray. All three wear gray tops with gray skirts, trousers or joggers, gray tights or socks, black flats or sneakers, mouse-ear headbands and long fabric tails fastened firmly at the waistband. Dark sunglasses are the joke that makes the nursery rhyme click. Gray and pink makeup around the nose and fine whiskers in a face-safe pencil finish the face. Make the canes from decorated cardboard tubes, not anything rigid. One honest warning: dark lenses at night make walking genuinely hard, so I'd wear them for photos and push them up on your head between stops. Mixing a dress, a jumpsuit and a sweater keeps each mouse an individual.
9. Three Little Pigs Trio Costume

Soft pink makes the Three Little Pigs a cute, comfortable trio. One person wears a pink dress, another a pink jumpsuit and the third a pink sweater and trousers. Pig-ear headbands, curly fabric tails, pink tights or socks and white or pink sneakers go on all three. Rosy blush, a pink nose and a few freckles keep it cheerful. Each pig carries something for straw, sticks or bricks: a raffia bundle, painted craft sticks or foam bricks, all far lighter than the real thing. Pinks rarely match across three shops, and I actually like that; slightly different shades read as three siblings. Pastel cardigans or long-sleeve layers handle the cold.
10. Rock Paper Scissors Trio Costume

Rock, paper, scissors is a funny DIY idea that needs almost no matching clothes. Everyone starts in plain black shirts, black trousers and comfortable sneakers so the handmade pieces stand out. Rock wears a big gray foam-board shape textured with crumpled paper, plus silver highlights on the face. Paper wears a white rectangular sandwich board with pale blue lines, sleek hair and clean makeup. Scissors wears two crossed silver cardboard blades with rounded ends fixed to a light vest, so nothing needs carrying. Gray, white and metallic headbands link them. I mock up each sign in newspaper first and walk through a doorway in it; if you have to turn sideways, it's too big for a party.
11. Traffic Light Trio Costume

Red, yellow and green is about the easiest color-coded trio there is. Each person dresses head to toe in one shade, for example a red dress with sneakers, a yellow jumpsuit with ankle boots, and green trousers with a green sweatshirt. A black circle panel on the front of each outfit turns the color into a signal lens. Graphic eyeliner, eyeshadow or cheek dots can follow each person's color. Leave the hair natural or add matching clips. A light cardboard traffic-light frame the three can hold together makes the group photo. Reflective tape around the cuffs is both on-theme and genuinely useful for walking home after dark.
12. Neapolitan Ice Cream Trio Costume

Strawberry, vanilla and chocolate make a soft pastel trio with room for personal style. Strawberry wears pink, vanilla cream and chocolate a rich brown, in dresses, matching sets or sweaters with tulle skirts. White sneakers or ballet flats and felt sprinkle headbands tie them together. Pink-toned makeup for strawberry, champagne shimmer for vanilla and warm bronze for chocolate is a nice touch. Buns shaped like scoops, or soft curls with cherry clips, finish the hair. Quilted tan cone-shaped bags are the clever prop. If you can, match the hemlines; three different lengths make it look like three separate outfits instead of one dessert.
13. S’mores Trio Costume

Graham cracker, chocolate and marshmallow turn into a clever food costume using simple squares. The graham cracker wears tan clothing with a foam-board panel marked with dotted cracker lines. Chocolate wears dark brown with a rectangular panel divided into candy-bar squares. Marshmallow wears a white puffer vest, white trousers and white sneakers for a soft, rounded shape. Neat natural hair with tan, brown or pearly clips and fresh makeup suit all three. The best bit is the photo: marshmallow and chocolate stand between two detachable cracker panels to build the s'more. I attach those panels with wide ribbon straps over the shoulders, and round every foam corner so it doesn't jab the person beside you.
14. Bacon Eggs And Toast Trio Costume

A breakfast trio gets a laugh at any party. Bacon wears a red-and-pink striped tunic over black leggings and red sneakers. Eggs wears white under a big rounded white panel with a yellow felt yolk in the middle. Toast wears tan with a brown-edged foam tunic shaped like a bread slice. Chef-style headbands or tiny utensil clips tie the three together, and makeup can stay natural. A cardboard menu or a soft plush frying pan with no hard edges is the prop. I always wear fitted layers under food panels, because panels slide around on a loose sweatshirt. Keep every shape above the knee so sitting and walking stay easy.
15. Ketchup Mustard And Hot Dog Trio Costume

Ketchup, mustard and a hot dog are bold, cheap and very simple. Ketchup wears red with a pointed bottle-cap hat and a white label panel, and mustard repeats it in yellow. The hot dog wears a tan jumpsuit or dress with a brown center panel and a wavy red-and-yellow felt squiggle. Sneakers in each person's color, plus red, yellow or warm brown makeup touches, keep it coordinated. High ponytails, buns or short textured styles sit fine under the light hats. A cardboard picnic tray or a checked fabric bag finishes the group. Felt bends where cardboard cracks, so I'd make the squiggle and label from felt and save cardboard for the hats.
16. Sun Moon And Star Trio Costume

Sun, moon and star is a celestial trio that needs very little building. The sun wears a gold or yellow dress, a ray headband, golden makeup and metallic flats. The moon takes a silver or pale-blue jumpsuit, a crescent headpiece, cool shimmer around the eyes and silver sneakers. The star wears navy scattered with gold felt stars, a star clip and navy ankle boots. Small orb bags or a battery fairy light make good accessories. Skip long trailing fabric that ends up under someone's shoe. I match the headpiece sizes most of all; if the sun's rays are twice as tall as the moon's crescent, the three stop looking like a set.
17. Rainbow Cloud And Sunshine Trio Costume

Rainbow, cloud and sunshine is cheerful for friends, families or a teaching team. The rainbow wears a multicolored striped dress, rainbow tights, bright clips and white sneakers. The cloud wears pale blue with soft white batting fixed to a light vest and headband, plus silver shimmer for raindrops. Sunshine goes yellow head to toe, with a felt-ray collar, golden eye makeup and yellow flats. Small weather signs or felt raindrops are optional. Batting sheds and catches on everything, so I baste it onto the vest in clumps rather than gluing loose fluff, and keep it away from the face and armholes. Matching white shoes link the three in a full-length photo.
18. Bee Butterfly And Ladybug Trio Costume

A bee, butterfly and ladybug make a colorful garden trio that can go cute or dressy. The bee wears black-and-yellow stripes, a black skirt or trousers, antennae, sheer wings and black boots. The butterfly wears a bright dress or jumpsuit with large fabric wings, bright eye makeup and matching flats. The ladybug wears a red-and-black spotted outfit, rounded wings, antennae and red sneakers. I hold every wing set to shoulder width for a crowded party; wider wings knock drinks off tables. Flower clips and rosy makeup unify the group, and small watering-can bags or fabric flowers give each person somewhere to keep a phone and keys.
19. Lion Tiger And Bear Trio Costume

Lion, tiger and bear are cozy picks for a cold night. The lion wears a tan sweatsuit, a furry mane headband, a fabric tail and brown sneakers, with golden makeup, a dark nose and fine whiskers. The tiger wears orange with black felt stripes, rounded ears, a striped tail and black shoes, plus orange eye makeup. The bear wears a brown hoodie and trousers, round ears, a short tail, brown boots, warm brown blush and a soft painted nose. Paw-shaped bags or a little woodland sign work as props. Fleece across all three makes them feel like a set and lets each body type choose a comfortable cut. Tiger stripes look better tapered at both ends, so I cut them as long thin wedges rather than straight bands.
20. Scarecrow Crow And Pumpkin Trio Costume

This harvest trio mixes classic Halloween imagery with warm fall layers. The scarecrow wears patched overalls, a plaid shirt, raffia cuffs, a floppy hat and brown boots, with stitched lines drawn around the mouth, not wounds. The crow wears a black top, a feather-trimmed cape, black trousers, sleek dark hair, smoky gray makeup and black shoes. The pumpkin wears an orange dress or sweatshirt with black felt features, green tights, a curled vine headband and orange sneakers. A small basket of fake leaves or foam pumpkins finishes them. Raffia and feathers both shed, so I trim them short and give the costume a good shake outside before anyone gets in the car.
21. Ghost Vampire And Witch Trio Costume

Ghost, vampire and witch are three Halloween classics that don't need matching outfits. The ghost wears a flowing white dress or white trousers with a draped cape, pale makeup, white hair spray and silver flats. The vampire wears black with a red-lined cape, slicked-back hair, soft pale makeup and polished black shoes. The witch wears a purple or emerald dress, a pointed hat, striped tights, ankle boots and smoky eyeshadow in her color. Small lanterns, an old-looking book and a light broom are the props. Skip full face coverings so everyone can see. White hair spray can leave a residue on dark collars, so the ghost is the right person to wear it, and I'd spray it outside.
22. Skeleton Mummy And Pumpkin Trio Costume

Skeleton, mummy and pumpkin bring plenty of Halloween without anything gory. The skeleton wears a black sweatsuit with white felt bones, black sneakers and simple black-and-white face makeup. The mummy wears cream clothes loosely wrapped in gauze strips, beige shoes and soft neutral shading. The pumpkin wears orange separates with a green collar, a leaf headband, orange shoes and cheerful black features on the shirt. Candy buckets in black, cream and orange tie them together. Loose gauze unwinds within an hour, so I tack each strip to the base layer with a few hand stitches or safety pins and make sure nothing trails near the feet.
23. Past Present And Future Trio Costume

Past, present and future is a flexible idea that doesn't depend on any character. The past wears a vintage-style midi dress or suspenders, curled hair, classic makeup and lace-up shoes. The present wears a current casual outfit: jeans, a plain tee, sneakers and natural hair. The future wears silver trousers, a metallic jacket, sleek hair, graphic silver liner and white boots. Labeled clock necklaces or headbands explain the concept, and each person can carry a cardboard clock set to a different time. I'd repeat one silver belt or cuff across all three; it's a small piece, but it ties three different eras into one group.
24. 1920s 1970s And 1990s Trio Costume

Three decades, the 1920s, 1970s and 1990s, work best with real period clothes rather than cartoon versions. The 1920s person wears a fringed knee-length dress, a pearl necklace, a jeweled headband, bobbed hair, soft red lipstick and low heels. The 1970s person takes flared trousers, a patterned blouse, platform boots, feathered hair and warm bright eyeshadow. The 1990s person wears straight-leg jeans, a fitted tee under an oversized plaid shirt, small hair clips, brown-toned lipstick and chunky sneakers. Decade cards or fake record sleeves help in photos. Matching black bags keep the three balanced. Thrift stores are full of real 70s and 90s pieces, and I'd always pick stable shoes over historical accuracy.
25. Porcelain Rag And Wind-Up Doll Trio Costume

Three dolls give you three textures and one makeup theme. The porcelain doll wears a pastel lace dress, a curled wig, knee socks, Mary Janes and painted rosy cheeks. The rag doll takes a patchwork dress or overalls, striped tights, yarn pigtails, freckles and flat boots. The wind-up doll wears a structured metallic or jewel-tone dress, a big cardboard key on a belt, sleek curls, mechanical liner details and low boots. Matching bows at each neckline connect them. I'd keep the makeup sweet, not cracked, unless the whole group wants a scary night. Mount the wind-up key on a belt, not sewn to the dress, so it comes off for sitting and the car ride.
26. Ringmaster Clown And Acrobat Trio Costume

A circus trio shares red, black and gold while giving each person a big role. The ringmaster wears black trousers, a red tailcoat with gold trim, a top hat, polished boots and bold red lipstick. The clown wears a bright ruffled jumpsuit, suspenders, striped socks, sneakers and cheerful face dots instead of full white makeup, which some guests find unsettling. The acrobat wears a fitted long-sleeve unitard under a short tulle skirt or high-waisted shorts, wrist cuffs, sleek hair and soft dance shoes. A foam hoop, paper tickets or a light megaphone are the props. Skip rigid props and clown shoes. Gold stars on all three costumes make them read as one show.
27. Pirate Mermaid And Sailor Trio Costume

A pirate, mermaid and sailor make an ocean trio with three different shapes. The pirate wears black trousers, a white blouse, a striped sash, a brown vest, a headscarf, tall boots, smudged eyeliner and a cardboard treasure map. The mermaid wears a shimmering fitted skirt, a sea-green top, wavy hair, pearly makeup, shell clips and metallic flats. The sailor wears white trousers, a navy striped shirt, a red scarf, a sailor cap and white sneakers. A treasure-chest bag, fabric fish or cardboard ship's wheel works better than anything sword-shaped. I check the mermaid skirt by climbing a flight of stairs in it; many sequin mermaid skirts are too narrow at the knee to walk in. Navy and gold details carry through all three.
28. Astronaut Alien And Planet Trio Costume

Space gives you simple shapes and lots of reflective material. The astronaut wears a white jumpsuit with silver patches, a light helmet-style headpiece, silver eye makeup and white sneakers. The alien takes a bright green or purple outfit, an antenna headband, metallic face accents and matching boots. The planet wears blue or purple with a foam ring fixed around the waist, star clips and glittery flats. Battery lights or cardboard mission badges are the props. I'd keep the planet ring narrow enough for doorways, and leave the astronaut's face fully open, since a closed helmet fogs and muffles speech within minutes. Silver belts and reflective tape make the three look like one crew.
29. Detective Trio Costume

Three detectives make an understated costume for adults, teens, teachers or coworkers. Give each one a different silhouette: a tan trench with trousers, a plaid blazer with a pleated skirt, and a dark cardigan with tailored trousers. Button-down shirts, sensible loafers and neutral scarves tie them together. Hair can be waved, tied back or tucked under soft-brim hats, and makeup stays polished and natural. Each carries a magnifying glass, a pocket notebook and a paper evidence envelope, with matching name badges or question-mark pins to make the idea clear. The coats come off indoors and the shirts and pins still tell the story, which is why I suggest it for offices.
30. Gardener Flower And Bee Trio Costume

A gardener, flower and bee tell a small connected story, which suits families. The gardener wears overalls, a plaid shirt, a sun hat, gardening gloves and rubber-style boots, and carries a clean plastic watering can filled with fake flowers. The flower wears a green dress or jumpsuit with a bright petal collar, leafy wrist cuffs, floral makeup and green flats. The bee wears black-and-yellow stripes, soft wings, antennae, black trousers or a skirt and black sneakers. One matching flower on every costume links them. Leave real soil, plants and tools at home. I'd stiffen the petal collar with a layer of iron-on interfacing so it doesn't flop down by mid-evening.
31. Chef Server And Diner Trio Costume

A chef, a server and a very excited diner build a restaurant scene. The chef wears black trousers, a white double-breasted jacket or white shirt, a neckerchief, a chef's hat and non-slip black shoes. The server wears a white shirt, a black apron, black trousers or a skirt, a bow tie and comfortable loafers. The diner goes bright and casual with a paper bib, funny glasses, sneakers and an oversized cardboard menu. The chef and server keep hair neatly tied back, and makeup stays fresh. A light tray of felt food and an order pad are the props. I'd add one checked accessory to each person, such as a scarf, an apron pocket or a bag, since that pattern is what tells people it's a restaurant.
32. Pencil Eraser And Notebook Trio Costume

School supplies make an easy DIY trio for classrooms, campus parties or family events. The pencil wears yellow with black trim, a pink headband for the eraser end and a pointed tan hat. The eraser wears an all-pink dress or tracksuit with a blue paper-wrapper belt. The notebook wears white under a rectangular foam panel with blue horizontal lines and one red margin line. Color-matched makeup, comfortable sneakers and natural hair or matching clips finish them. A small backpack or an oversized paper clip bent from flexible tubing makes the prop. Cut the notebook panel short enough to sit down in. The repeated yellow, pink and blue across all three is what turns them into a set.
33. Red Blue And Yellow Crayon Trio Costume

Three crayons in red, blue and yellow use almost the same costume three times. Each person wears a solid-color dress, jumpsuit or sweatsuit, with black felt bands around the wrists, waist and lower legs for the wrapper. Cone hats in each color make the crayon tips. Matching tights or socks and sneakers finish the bodies, and a sweep of eyeliner plus a bright lip tint in the same color is enough makeup. Cardboard coloring pages or crayon-box buckets are good props. I make all three cone hats from one paper pattern, so they come out the same height, and pin the black bands at the same points on everyone even if one person is in a dress and another in a sweatsuit.
34. Laughing Heart Eyes And Cool Emoji Trio Costume

Emoji faces are a modern trio built on yellow clothes and easy symbols. All three wear yellow sweatshirts, dresses or jumpsuits with black leggings and yellow or white sneakers. The laughing face adds big felt tears and a wide grin to the shirt, heart eyes uses red felt hearts and red clips, and the cool face wears oversized black sunglasses with a relaxed smile panel. Golden shadow, rosy cheeks and gloss keep the human faces simple. Round yellow bags hint at the shape without bulky round costumes. I attach the facial pieces with hook-and-loop dots, so the sweatshirts go back to normal clothes the next day, and add matching yellow headbands to tie the set together.
35. Pac-Man And Two Ghosts Trio Costume

Pac-Man and two ghosts are a nostalgic arcade trio built from foam board and felt. Pac-Man wears yellow under a round yellow sandwich board with an open mouth. The ghosts wear red and blue outfits with scalloped felt tunics, big cartoon eyes and matching sneakers. Simple color-matched makeup and natural hair keep the faces free. White foam dots can be carried or stuck to black crossbody bags as the game path. I'd keep the boards narrow with every edge rounded. Point the ghosts' eyes in different directions for a laugh, and put everyone in black base layers so the bright shapes pop.
36. Tetris Blocks Trio Costume

Three Tetris blocks make a graphic costume you can build around favorite colors. Everyone wears a black base layer and black shoes. Cut light foam-board tunics in three block shapes, such as an L, a T and a straight line, paint each a different bright color and outline every square in black. Matching eyeliner or clips add color without covering the face, and small foam cubes can become bags or props. Keep every block above the knee and not much wider than the shoulders. The straight line is the awkward one; I'd give it to the tallest person and wear it vertically, or it blocks everyone's arms. For photos, stand so the three blocks look like they're slotting together.
37. Clue Character Trio Costume

Miss Scarlet, Colonel Mustard and Mrs. Peacock give you a color-coded mystery with vintage charm. Miss Scarlet wears a red midi dress, red heels or flats, soft waves and classic red lipstick. Colonel Mustard wears mustard trousers, a matching blazer, a bow tie, neat hair and brown dress shoes. Mrs. Peacock wears a teal or royal-blue dress, a feather hair piece, blue eye makeup and low heels. Clue cards, magnifying glasses, sealed envelopes and a game-board bag are good props; I'd leave the game's weapons out, since realistic-looking ones aren't welcome at a lot of parties and venues. Similar vintage shapes and gold jewelry link the three, while the colors keep each role clear.
38. Dorothy Scarecrow And Tin Man Trio Costume

Dorothy, the Scarecrow and the Tin Man work for nearly any age mix. Dorothy wears a blue gingham pinafore over a white blouse, braids with blue ribbons, rosy makeup and sparkly red flats. The Scarecrow takes patched brown trousers, a plaid shirt, a rope belt, a soft hat, raffia accents, stitched face lines and brown boots. The Tin Man wears silver trousers, a silver top, a metal-look cap, silver face highlights and gray sneakers. A picnic basket, a fabric diploma and a light silver heart are the props. Silver body paint is hard to remove and can irritate skin over a long night, so I'd use silver clothing and a light shimmer instead. A little blue ribbon on all three ties them together.
39. Alice Mad Hatter And Queen Of Hearts Trio Costume

Alice, the Mad Hatter and the Queen of Hearts each come with strong details of their own. Alice wears a pale-blue dress, a white apron, a black headband, white tights and black Mary Janes. The Hatter takes patterned trousers, a bright vest, an oversized bow tie, a colorful jacket, a top hat and lace-up boots. The Queen wears a red-and-black dress with hearts, a gold crown, red lipstick, heart-shaped eye makeup and black heels or flats. Teacups, playing cards and a small white rabbit plush are the props. I'd ask the Queen to keep her skirt narrow enough to walk in, and put a red heart somewhere on all three so they look like one group.
40. Regina Gretchen And Karen Trio Costume

Regina George, Gretchen Wieners and Karen Smith suit friends who'd rather wear outfits than full costumes. Build coordinated early-2000s school looks with fitted cardigans, pleated skirts, small shoulder bags and comfortable heels or flats. Regina wears pink with long blonde hair and glossy makeup. Gretchen takes burgundy or plaid, long brunette waves and polished neutral makeup. Karen wears a pale pink or lavender top, blonde hair or a wig and soft shimmer around the eyes. Handmade name tags, pink notebooks or flip-phone props help strangers place you. Layer the cardigans over camisoles for warmth. Without the pink and the name tags, this trio can pass for three friends on a night out, so I'd lean into both.
Foam Board Panels That Get Through a Door
Eight of these trios rely on a panel or sandwich board: rock, paper, scissors, the s'more, breakfast, the notebook, Pac-Man and Tetris. These are where homemade costumes most often go wrong, and a few habits fix almost all of it.
- Measure the wearer, not the idea. I hold a tape across the shoulders and keep the panel within a couple of inches of that width, and above the knee.
- Round every corner. Trace around a mug and cut it off; square foam-board corners poke people in a crowd and dent the moment you bump a wall.
- Use wide ribbon or cotton webbing for shoulder straps. Thin string cuts into the shoulders within an hour.
- Glue with something rated for foam, or use tape on the inside. Hot glue melts some foams and goes brittle in cold air outside, which is when panels tend to drop off.
- Plan for rain. Paper-covered foam board warps and peels when wet, so for an outdoor night I'd paint it or cover it in felt or craft foam instead.
Finally, sit down in it. If the panel jams against your knees or the chair back, trim the bottom or hinge it with tape so it folds up when you sit.
Three Wigs and One Car
Several of these trios need more than one wig, and wigs are the piece that looks worst by the end of the night. Brush each one out and set it with a little spray before you leave, wear a wig cap with a few pins, and keep synthetic wigs away from candles and heaters, because the fibres frizz and melt. Store them in separate bags on the way home so the colors don't tangle together.
Agree on One Shared Detail Before Anything Else
The trio costumes that work give all three people their own recognizable role while sharing one color, texture, shape or story. The list above covers character groups, classic monsters, food pairings, animals, puns and easy DIY themes for different ages and comfort levels. Before you decide, talk about budget, the weather, shoes and how much crafting each person is willing to take on. Splitting the shopping list stops two people buying the same thing at the last minute. Try the big props at home, fasten every accessory and take a full group photo before you leave. Above all, pick a theme all three of you are excited to wear, because a confident trio always looks better than three uncomfortable people.
