A good four-person theme gives every person a character people can name, with nobody stuck as the spare. The list below mixes classic characters, cartoons, food jokes, decade looks and simple DIY ideas, and each entry covers clothing, hair, makeup, props and shoes. Four is a forgiving number to dress: colours balance, roles pair off neatly and photos frame well. Most of these come together from closet basics, thrift finds, felt, cardboard and inexpensive accessories, for friends, relatives, coworkers or older kids. I'd read through with your group's real limits in mind, such as budget, how much makeup people will wear and how far you're walking, before anyone falls for a theme.

Uniform Groups Versus Cast Groups
Every four-person idea below falls into one of two types, and knowing which you want saves a lot of back-and-forth in the group chat.
Uniform groups
Ghostbusters, Turtles, crayons and Teletubbies put everyone in the same base outfit with one changing detail, usually colour. They're the easiest to shop for, the most forgiving across different sizes and the quickest to make, because you're repeating one pattern four times. I steer groups toward these when time is short or when someone dislikes standing out.
Cast groups
Oz, the Addams Family, Clue and Wicked give each person a different character with a different outfit. They're more fun to wear and more work to plan, and they only read as a group when all four turn up. If one member might cancel, a cast group falls apart, while a uniform group of three still makes sense.
A third option sits in between: three matching characters plus one contrast, like the Powerpuff Girls with Mojo Jojo or Pac-Man with his ghosts. It suits a group where one person wants a bigger or very different role.
1. Wizard Of Oz Group Costume

Oz is the group I'd suggest when four people have very different comfort levels, because the roles range from a simple dress to a full metallic face. Dorothy wears a blue gingham dress over a white blouse, braids tied with blue ribbons, rosy makeup, red flats and a small basket. The Scarecrow needs patched brown clothing, a floppy hat, straw-coloured yarn at the cuffs and brown boots. The Tin Man takes silver clothing, metallic face makeup, silver sneakers and a cardboard funnel hat, so give that role to whoever enjoys makeup most. The Lion wears a warm brown sweatsuit, furry ears, a yarn mane, soft whiskers and brown shoes. A yellow cardboard road sign or fabric poppies make the story clear.
2. Scooby-Doo Group Costume

This version swaps Shaggy for Fred, which gives the crew a cleaner, preppier line-up. Velma needs an orange sweater, red skirt, knee socks, loafers, a short brown wig and square glasses. Daphne combines a purple dress with a green scarf, lavender flats, red hair and soft purple makeup. Fred wears a white sweater, blue pants, an orange neck scarf, blond hair and brown shoes; the scarf knotted at the side of the neck is the small detail that separates him from a man in a sweater. Scooby uses a brown hoodie and joggers with felt spots, floppy ears, a blue collar, a little face paint and sneakers. Magnifying glasses, flashlights and a light cardboard van sign finish it.
3. Teenage Mutant Ninja Turtles Group Costume

Turtles need almost no sewing, which is why teen groups like them. Everyone starts with green T-shirts, leggings or joggers, green face makeup and green or black sneakers, then adds a brown felt chest panel and a light shell of painted cardboard or foam. Red, blue, purple and orange eye masks keep the roles separate. I tie those masks from soft jersey rather than stiff felt, since jersey stretches around the head without pressing on the nose. Green beanies or slicked-back hair finish the colour. Carry pizza boxes or foam sewer lids instead of weapons, and brown elbow and knee pads add texture for an active party or trick-or-treat route.
4. Ghostbusters Group Costume

Four matching paranormal investigators suit friends who want one uniform rather than four characters. Dress everyone in tan utility jumpsuits, or khaki shirts with matching cargo pants, then add black belts, fingerless gloves, dark boots and homemade name patches. Hair can stay natural, and a little smudged gray eyeshadow suggests a long night of ghost chasing. Build the packs from painted cereal boxes, plastic tubing and backpack straps. I pad the straps with a strip of fleece, because thin straps dig in after an hour even on a light pack. A paper ghost detector, a flashlight or a plush ghost goes in each hand, and matching warning labels and shoulder patches tie the four together while sizes and shoes vary freely.
5. Fantastic Four Group Costume

A superhero team of exactly four is hard to beat for a group this size. Matching royal-blue tops and pants carry a white circle with a black number four on each chest, plus black belts, gloves and boots. The rocky hero adds orange foam panels, and the flame hero wears a short blond wig with orange-red fabric accents. The stretchy leader carries curled blue ribbon streamers, while the invisible heroine wears shimmery silver makeup with sheer organza around her shoulders. Organza frays badly at a cut edge, so I run a narrow hem or a line of fray stopper around it first. Sleek hair, blue eye makeup and silver highlights finish the comic-book look, with no masks or tight bodysuits needed.
6. Inside Out Emotion Group Costume

These four emotions are colour plus expression, and the expression part is free. Joy wears a yellow dress, blue wig, bright makeup and yellow flats with a glowing memory orb. Sadness takes a blue sweater, loose blue pants, round glasses, a short blue wig, blue sneakers and a tissue box. Anger needs a white shirt, red tie, dark trousers, red face makeup, red shoes and a flame-shaped felt headpiece. Disgust wears a green dress, purple scarf, green wig, pink lipstick and green flats. Coloured wigs are where cheap versions show, so I brush them out and snip any straggling fibres before the night. Clear ornaments painted in pastel shades become shared memory props, and asking everyone to hold their emotion's face in photos does a lot of the work.
7. Super Mario Group Costume

Mario, Luigi, Peach and Toad cover the classic game line-up. Mario and Luigi wear red and green shirts under denim overalls, matching caps, white gloves, brown shoes and removable felt mustaches. Peach needs a pink dress, blond wig, crown headband, blue earrings, rosy makeup and comfortable pink flats. Toad wears white pants, a blue vest, brown shoes and a homemade white mushroom hat with large red felt circles. I fix felt mustaches with skin-safe double-sided tape; it holds through talking and eating and peels off without a sting. Cardboard coins, stars or question-mark blocks make easy props, and breathable layers matter if you'll be outside most of the night.
8. Toy Story Group Costume

Woody, Buzz, Jessie and Bo Peep give four distinct shapes that still clearly belong in one toy box. Woody wears a yellow plaid shirt, jeans, cow-print vest, cowboy hat, red bandanna and brown boots. Buzz needs a white outfit with green and purple felt panels, a purple hood, silver makeup details and white sneakers. Jessie takes jeans, a white shirt with yellow cuffs, a red hat, a braided red wig and boots. Bo Peep wears a pale blue jumpsuit or dress, a pink cape, blond hair and blue flats, with a crook made from foam tubing. I slide that tubing over a light garden cane bent at the top so the hook keeps its curve. Cardboard toy-box labels add a fun extra.
9. Alice In Wonderland Group Costume

Alice, the Mad Hatter, the Queen of Hearts and the White Rabbit leave plenty of room for each person's taste. Alice wears a blue dress, white apron, black headband, blond hair, striped tights and black flats. The Mad Hatter needs a colourful blazer, patterned trousers, an oversized hat, bright eye makeup, wild hair and ankle boots. The Queen gets a red-and-black gown with heart appliqués, dramatic lipstick, a gold crown and black shoes, and the Rabbit white clothing with furry ears, red accents, whiskers and white sneakers. I cut the hearts from felt and use fabric glue plus a few tacking stitches at the points, which are always the first part to lift. A cardboard clock, teacups, paper roses and little 'drink me' tags on reusable bottles finish the scene.
10. Addams Family Group Costume

The Addams Family is the one black-and-white group here, a sharp contrast to the brighter themes. Gomez wears a black pinstripe suit, white shirt, dark tie, combed hair, a drawn-on mustache and dress shoes. Morticia needs a long black dress, straight black wig, deep red lipstick, pale makeup and pointed flats. Wednesday takes a black dress with a white collar, braids, neutral makeup, black tights and loafers, and Pugsley a black-and-white striped shirt, dark shorts, knee socks and black sneakers. Long straight black wigs show tangles more than any other kind, so I keep a wide-toothed comb and a small spray bottle of water with a drop of conditioner in the bag. Black roses, a framed portrait or a rubber hand make playful props.
11. Powerpuff Girls And Villain Group Costume

Three heroines and one villain is a smart answer for a group of four where only three want the cute roles. Blossom wears a pink dress, a red bow, an orange ponytail, pink eye makeup and black flats. Bubbles needs a blue dress, blond pigtails, blue eyeshadow, white knee socks and black shoes, and Buttercup a green dress, short black wig, green makeup and matching flats. Mojo Jojo takes white pants, a blue tunic, a purple cape, green face makeup, white gloves and a tall purple-and-white foam helmet. I build that helmet around a snug headband so it sits on the head instead of sliding forward. Oversized felt eyes clipped to handbags or belts add a cartoon touch without covering faces.
12. Stranger Things Group Costume

This group brings in Max and Steve, and it comes together mostly from secondhand clothing. Eleven wears a pink dress, blue jacket, striped socks, white sneakers and short hair or a brown wig, carrying an empty waffle box. Max needs a colourful windbreaker, graphic shirt, denim shorts, red hair, headphones and high-tops, and Dustin a printed T-shirt, denim jacket, baseball cap, curly hair and a backpack. Steve's blue sailor-style work top and matching shorts are the hardest pieces to find, so I'd make his top from a plain blue shirt with a white bias-tape collar, then add styled brown hair and white socks. Shorts are cold in late October, so plan tights or base layers. Walkie-talkies, flashlights and arcade tokens fill out the props.
13. Beetlejuice Group Costume

Beetlejuice, Lydia, Delia and Astrid make an offbeat group held together by black, white and red. Beetlejuice needs a black-and-white striped suit, white shirt, messy pale hair, green-and-purple eye makeup and black boots. If a striped suit is hard to find, I'd sew simple elastic-waist trousers from striped fabric and pair them with a thrifted striped blazer, since painted or taped stripes smear and peel by the end of the night. Lydia wears a flowing red dress or black lace dress, teased dark hair, smoky makeup and ankle boots. Delia goes sculptural in black with bold accessories, red lipstick and an angular hairstyle, and Astrid takes a plaid skirt, striped cardigan, dark tights and loafers. Miniature model houses and odd framed art make harmless props.
14. Wicked Group Costume

Elphaba, Glinda, Fiyero and the Wizard bring a stage show's drama to a group of four. Elphaba wears a long black dress, pointed hat, green face and hand makeup, braided or wavy black hair and sturdy black boots. Glinda needs a sparkling pink gown, blond curls, a silver crown, soft pink makeup and glittery flats. Fiyero takes cream trousers with a fitted blue or green jacket, polished hair and tall brown boots, and the Wizard an emerald coat, patterned vest, top hat, gray hair and dress shoes. Green on the hands rubs off on everything, so I'd suggest thin green gloves for Elphaba if she'll be eating or holding drinks. A bubble wand, a green book and a small hot-air balloon finish it, and light fabrics keep the gowns wearable.
15. Mean Girls Pink Group Costume

This pink friend group is built from everyday clothes rather than character replicas, which keeps the cost down. One person wears a pink cardigan, white tank, plaid skirt, blond wig, glossy makeup and pumps. The second takes a strapless pink dress, dark wavy hair, matching lipstick and flats; the third a pink polo, pleated skirt, long brown hair and sneakers; the fourth an oversized pink shirt, dark skirt, straight brown wig and loafers. Strapless dresses need constant hitching over an evening, and I'd add clear straps or a fitted cardigan for anyone who'll be dancing. Notebooks, mirrors, pink pens and handmade school badges explain the theme. Mixing blush, bubblegum and hot pink gives variety while the palette stays obvious.
16. Golden Girls Group Costume

Dorothy, Rose, Blanche and Sophia suit a group that wants comfort and laughs in equal measure. Dorothy wears a long printed dress, a loose gray cardigan, a short gray wig, statement earrings and low pumps. Rose takes a pastel blouse, floral skirt, pearls, a curled blond wig and flats. Blanche chooses a bright flowing dress, gold jewellery, styled auburn hair, polished makeup and low heels, and Sophia a patterned house dress, buttoned cardigan, short white wig, glasses, handbag and supportive shoes. Vintage brooches and padded shoulders connect all four. Short curled wigs flatten in a bag, so I carry them stuffed with tissue and fluff them with fingers, not a brush. Coffee mugs and a cheesecake box make light props.
17. ABBA Group Costume

A shimmering disco quartet gives the group plenty of movement for dancing. Two people wear white bell-bottom jumpsuits with silver or blue embellishments, platform-style boots, feathered hair and sparkling makeup. The other two take flared trousers with ruffled shirts, metallic vests, neck scarves and white boots. Blond and brown wigs create contrasting stage personas, and I secure each one with bobby pins crossed in an X at the sides and back, which holds through a lot of dancing. Toy microphones, silver star cutouts and a cardboard record make easy props. Stretch fabric and stable shoes keep everyone moving, and matching sequins at collars, cuffs and hems make the four look matched under party lights.
18. Beatles Group Costume

Four matching musicians make a straightforward costume with one clear silhouette. The colourful marching-band era uses fitted jackets in red, blue, yellow and pink with black trousers, white shirts, gold trim and polished black shoes. Each person wears a dark mop-top wig or smooths their own hair into a rounded shape, with subtle liner and neat sideburns. If proper band jackets are out of reach, thrifted blazers take braided cord, felt shoulder pieces and shiny buttons well. I hand-stitch the cord rather than glue it, because glue soaks through and marks the jacket. Cardboard guitars, a toy drum or vintage-style microphones beat bulky instruments, and matching trousers and shoes balance the four jacket colours.
19. Teletubbies Group Costume

Teletubbies come down to four bright monochrome looks in purple, green, yellow and red. Wear matching hoodies with leggings or joggers, add a silver-gray felt rectangle to each stomach, and shape the head pieces from foam attached to matching headbands. Soft makeup is enough: rosy cheeks, coloured eyeshadow and a touch of highlighter. Foam antennae lean when the glue joint to the headband is tiny, so I wrap the base in a strip of fabric and glue the whole wrap, which gives a much bigger hold. Matching sneakers or slip-ons keep it practical, and a plush sun, flower or pinwheel adds to the setting. Each person can choose a hoodie shape and bottoms that suit their body while the colour code stays intact.
20. Crayon Box Group Costume

Four oversized crayons need nothing more than four colours and some felt. Each person chooses red, blue, yellow or green and wears a matching T-shirt dress, jumpsuit or top and pants, with black felt bands around the sleeves and lower legs for the label. Cardstock cones make the tips, and matching eyeshadow and lipstick carry the colour onto the face, with coordinating tights, sneakers or flats below. Cardstock creases the first time someone leans on a wall, so I line each cone with a second layer or use thin craft foam instead. One person can carry a cardboard box front labelled simply 'art supplies', or the group can stand inside a shared open-frame box for photos.
21. Four Seasons Group Costume

Each person takes a season here, joined by one flowing nature theme. Spring wears a pastel green dress, a floral crown, fresh makeup and light flats. Summer goes sunny in a yellow outfit, wide-brim hat, bright makeup and sandals with a paper sun. Fall combines an orange sweater with a brown skirt or trousers, a leaf headband, warm makeup and ankle boots, and winter wears white or icy blue with a silver cape, frosted makeup, sparkly hair pieces and white boots. Summer's wide brim catches the wind and blocks people's view, so I'd pin it with a hat elastic under the hair. Attach the flowers, leaves, rays and snowflakes securely, and use matching sashes or similar silhouettes to connect the four.
22. Weather Forecast Group Costume

A sun, a rain cloud, a rainbow and a snow cloud make a clever set for any age. The sun wears yellow with golden makeup, yellow sneakers and a foam-ray headpiece. The rain cloud is gray with a cloud hat, blue ribbon raindrops, silver eyeshadow and gray shoes, and the rainbow takes striped clothing, colourful makeup, a cloud headband and bright sneakers. The snow cloud wears white with a silver cape, a cotton cloud hat, snowflake makeup and white boots. I make cloud hats from fiberfill stitched onto a cheap knit beanie, which stays put far better than cotton glued to a headband. Forecast cards or cardboard temperature signs explain the theme. Keep anything hanging above knee level so nobody trips.
23. Fruit Salad Group Costume

Strawberry, orange, lemon and blueberry give a bright palette with very little crafting. Strawberry wears red with black felt seeds, a green leaf headband, rosy makeup and red sneakers. Orange needs an orange outfit, a leaf collar, a citrus-slice bag, matching eyeshadow and white shoes. Lemon takes a yellow dress or jumpsuit, a yellow headband, bright makeup and flats, and blueberry royal blue with a green crown, blue makeup and coordinating sneakers. The green leaf accents are what connect the four, so I cut every leaf from the same piece of felt to keep the green identical. Light fruit labels or a cardboard bowl-shaped photo frame for the group to hold finish the set.
24. Fast Food Meal Group Costume

A burger, fries, a soda and ice cream turn four people into one meal. The burger uses a tan tunic with layered brown, green, red and yellow felt, brown leggings and sneakers. Fries need a red box-shaped top, yellow foam strips, red pants and matching shoes. The soda wears a cylindrical red or blue tunic with a silver headband and a straw decoration, and the ice cream a pastel dress, a sprinkle-covered cone hat, colourful makeup, white tights and flats. For the fries box, I cut the armholes generously and test sitting down in it, because a stiff box rides up to the chin the moment you sit. Trays, napkins and big cardboard order numbers make simple props. Keep arms and knees free.
25. Breakfast Food Group Costume

A pancake, a fried egg, a cereal bowl and a carton of orange juice make a cheerful breakfast spread. The pancake wears tan with stacked foam circles, a yellow felt butter square, brown makeup and tan sneakers. The egg is a white tunic with a large yellow centre, a yellow headband, white leggings and white shoes. The cereal bowl takes a blue or white base covered in colourful foam circles with a spoon headpiece, and the orange juice an orange box-shaped tunic, a green straw headband, orange makeup, leggings and flats. Foam circles glued flat into a stack turn rigid, so I glue only the centre of each layer and leave the edges free to flex. A cardboard breakfast tray pulls the group together for photos.
26. Farm Animal Group Costume

A cow, a pig, a chicken and a sheep make a barnyard group without full mascot suits. The cow wears black-and-white spotted clothing, felt ears, soft nose makeup and black boots. The pig takes pink overalls or a pink sweatsuit with a curled tail, ear headband, rosy makeup and pink sneakers. The chicken needs a white outfit, a feather-trimmed cape, a red comb headband, yellow tights and yellow shoes, and the sheep cream clothing with a fluffy fabric, floppy ears, gentle face makeup and beige footwear. For the sheep, sherpa fleece reads as wool and doesn't shed the way glued cotton balls do. A basket, a fabric hay bundle or a cardboard barn sign completes each role, and open faces keep this one easy for families and school events.
27. Zookeeper And Safari Animals Costume

One zookeeper and three safari animals give flexible roles for a family or mixed-age group, and the zookeeper suits the adult who doesn't want ears. The zookeeper wears a khaki shirt, cargo shorts or pants, a wide-brim hat, binoculars and hiking boots. The lion takes brown clothing, a yarn mane, whiskers and brown shoes. The zebra needs striped clothing, upright ears, black-and-white face accents and black sneakers, and the giraffe yellow or tan with brown felt spots, a small horn headband, warm makeup and tan boots. Upright zebra ears flop unless something stiff is inside, so I sandwich craft foam between two felt layers. A cardboard zoo map makes a safe prop; leave out cages, chains and tight masks.
28. Circus Performer Group Costume

A ringmaster, a clown, a strong performer and an acrobat make a bright circus quartet. The ringmaster wears a red tailcoat, black trousers, a top hat, gold makeup and tall boots. The clown needs colourful overalls, a striped shirt, playful face makeup, a bright wig and big sneakers. The strong performer takes a striped top, high-waisted pants, a drawn curled mustache, boots and a foam barbell, and the acrobat a colourful fitted jumpsuit layered for coverage, sparkly eyes, a slick ponytail, ballet flats and ribbon hoops. True clown shoes trip people on stairs, so I'd use the clown's own sneakers with oversized painted toe covers. Repeating red, gold and black accents makes four different performers look like one show.
29. Classic Halloween Monster Group Costume

A vampire, a witch, a mummy and a werewolf give a traditional Halloween quartet that stays playful. The vampire wears a black suit or dress, a red-lined cape, slick hair, pale makeup and black boots. The witch takes a purple or black dress, a pointed hat, striped tights, green or smoky eyes and buckled shoes. The mummy's beige clothing gets securely attached fabric strips with neutral makeup and tan sneakers, and the werewolf brown plaid, faux-fur cuffs, animal ears, soft whiskers and brown boots. Faux fur sheds everywhere when you cut it with scissors, so I cut from the back with a craft knife through the backing only, which leaves the pile intact. A broom, a lantern, an old book and a faux moon finish it.
30. Fairytale Royal Court Costume

A princess, a prince, a fairy and a royal advisor form an elegant storybook court. The princess wears a pastel gown, curled hair, a delicate crown, rosy makeup and matching flats. The prince takes fitted trousers, a decorated jacket, a sash, a neat hairstyle and polished boots. The fairy needs a layered dress or jumpsuit, translucent wings, glittery makeup, a flower crown, ballet flats and a star-tipped wand, and the advisor a velvet robe, patterned vest, small hat and spectacles, carrying a scroll. Gold trim and jewel-toned accessories repeated across all four link the court. Loose glitter travels onto everyone nearby, so I'd use a cream glitter gel for the fairy instead. Foam crowns, flexible wings and short capes keep it light.
31. Greek Mythology Group Costume

Zeus, Athena, Aphrodite and Hermes rely on draped fabric, which is easy to get wrong in a crowd. Zeus wears a white tunic, blue sash, gray wig and beard, gold makeup, sandals and a foam lightning bolt. Athena takes a white dress, gold cape, braided hair, a metallic headband and a cardboard shield. Aphrodite chooses a flowing pink gown, long curls, pearls, luminous makeup and gold flats with artificial roses, and Hermes a short white tunic, red cape, winged headband, gold eye makeup and wing-decorated sneakers. I pin the drape at the shoulder with a large safety pin hidden under a brooch, then add a second pin at the waist, because one pin always works loose. Wear warm base layers underneath on cool fall nights.
32. Four Decades Group Costume

Four decades turn the group into a walking fashion timeline. The 1960s look is a geometric mini dress over tights, bouffant hair, winged liner and white boots. The 1970s takes flared jeans, a patterned shirt, feathered hair, warm makeup and platforms. The 1980s needs bright leggings, an oversized sweatshirt, a side ponytail, colourful eyeshadow, leg warmers and sneakers, and the 1990s loose jeans, a plaid shirt, a crop-length tee or fitted tank, brown lipstick and chunky sneakers. A bouffant collapses without help, so I tease the crown at the roots, set it with hairspray and smooth only the top layer over it. Cardboard decade signs, cassettes or records explain the order, and one repeated colour connects the four.
33. Pac-Man And Ghosts Group Costume

Pac-Man with three ghosts is a simple game costume built for exactly four. Pac-Man wears a bright yellow tunic cut into a rounded shape, yellow leggings, matching makeup and yellow sneakers. The ghosts take red, pink and blue oversized tunics with scalloped hems, black leggings, matching eyeshadow and coordinating shoes, with large white-and-black felt eyes on the front instead of over anyone's face. A round tunic only keeps its circle if the edge is stiffened, so I'd sew a length of boning into the hem or sandwich craft foam between two layers of fabric. Foam fruit, cardboard dots and a light maze frame make props. Keep tunics above the ankle for walking.
34. Clue Character Group Costume

Four colourful suspects make a polished mystery-game group. Miss Scarlet wears a red dress, dark curled hair, red lipstick and heels or flats. Colonel Mustard needs a mustard jacket, tan trousers, neat hair, a costume mustache and brown dress shoes. Mrs. Peacock takes a blue gown or pantsuit with feather accessories, dramatic blue eye makeup and blue shoes, and Professor Plum a purple blazer, patterned vest, glasses, purple accents and loafers. Feathers shed on a crowded night, so I stitch rather than glue the quills on Mrs. Peacock's pieces. Give everyone a name card and a harmless room prop, such as a candlestick-shaped flashlight, a notebook or a cardboard key, and leave realistic weapons at home.
35. Barbie Squad Group Costume

A Barbie-inspired squad lets four people pick different careers and aesthetics while staying in pink. The cowgirl wears a pink vest, flared pants, a white hat, curled hair, glossy makeup and boots. The roller-skater takes a neon bodysuit with shorts, a visor, bright makeup, knee pads and skates or sneakers; I'd go with sneakers anywhere with stairs, carpet or a crowd. The businesswoman wears a pink pantsuit, structured handbag, sleek ponytail and pumps, and the party look is a sequined pink jumpsuit, big hair, sparkly makeup and metallic heels. Oversized sunglasses, pink phones and cardboard doll-box frames make good props. Several shades of pink let each person stand out within one palette.
What Schools, Offices and Venues Tend to Allow
Plenty of groups wear these to a school event, an office party or a ticketed venue, and the rules there are usually stricter than at a house party. They vary, so check yours, but the same few points come up again and again.
- Masks that cover the whole face are often not allowed, because staff need to see who is who. Every idea here works with an open face.
- Realistic weapons, and anything that looks like one, are commonly banned. That's why the props here are foam, cardboard and plush.
- Very large costume pieces can be turned away at a busy door. Flat front panels and soft props get in where boxes don't.
- Schools often ask that costumes cover shoulders and midriffs and stay free of gore, so the Barbie, Mean Girls, ABBA and Greek looks may need a top layer or a different cut.
- Some workplaces ask for nothing that gets in the way of the job, so pieces you can take off and set on a desk are worth planning.
My habit is to build every costume so the most fragile or awkward piece comes off easily: the headpiece, the wings, the cape or the prop. That way you can adjust at the door instead of going home to change.
Sizing One Theme for Four Different Bodies
Four friends rarely share a size or a comfort level, and the theme shouldn't force anyone to choose between the two. Where a character calls for a fitted jumpsuit or a short dress, the colour does most of the recognising, so a looser top with leggings, a longer skirt or a tunic in the same shade reads the same from a few steps away. I'd find out early who wants more coverage, then match everyone by colour family rather than by identical garment.
Shoes deserve the same thought. Heels, platforms and skates turn up in several of these groups, and they're fine for a seated party but hard work on a long walk. Matching sneakers in the group's colours keep the line-up neat and get everyone home comfortably.
Which Four-Person Theme Suits Your Group?
A good group costume gives every person a whole role and the four of you one clear theme. These ideas cover character groups, cartoons, superheroes, food, animals, retro fashion and classic Halloween figures. Before settling, weigh up budget, weather, comfort, venue rules and how long everyone will be in costume. Share the shopping and crafting so one person isn't stuck making everything. Repeated colours, materials or accessories unite four different looks, while individual hair, makeup, shoes and props keep each role readable. Above all, choose a theme all four of you like, because people who enjoy their costume wear it better and stay in it longer.
