Most of the original costumes I style for adults start in an ordinary wardrobe, not a costume aisle. A sweatsuit, a pair of overalls, a trench coat or a set of pyjamas becomes the base, and a few handmade pieces in felt, cardboard or foam turn it into a joke or a small story. That approach costs less, and half of it goes straight back into your closet on the first of November. The list below mixes puns, wearable objects, odd jobs and gentle fantasy, and for each one I've said which piece carries the idea and where it tends to go wrong.
Raiding Your Wardrobe Before the Craft Store
Almost every idea below sits on one of a handful of plain bases. Look for these at home first, then at a thrift shop, and only then think about buying new.
- Matching sweatsuits in a single colour, which give you a clean, comfortable block for the weather, sun and plant ideas.
- Overalls and coveralls, the best base for any odd-job costume because the bib, pockets and straps give you places to attach things.
- Pyjamas and robes, for the sleepy jokes. Nobody complains about being too comfortable.
- A trench coat, cardigan or blazer, which instantly turns a pun into a person with a job.
- All-black layers, for anything where a panel, box or chest piece needs to stand out.
If the colour is close but not right, fabric dye is an easy fix for cotton, though it won't take on polyester. Wash any thrifted piece before you start decorating it, because new glue and stitching won't hold well on fabric that's still carrying old finishes or dirt. And try the base on with the shoes you'll actually wear, since everything you add later only makes it warmer and heavier.
1. Walking Weather Forecast Costume
Sky blue is the backdrop, so a matching blue sweatshirt and trousers are all the base you need. Attach felt clouds, suns, raindrops and snowflakes with safety pins from the inside, so you can move them around during the night as the "forecast" changes. That's the part guests enjoy. A cardboard temperature gauge goes on one sleeve and a small weather map on the front. A high ponytail with silver ribbon is plenty, though a pale blue wig adds punch if you like it. Shimmering blue eyes, little clouds at the temples, white sneakers and a microphone labelled "Weather Update" make you the presenter.
2. Human Vending Machine Costume
This one does well at parties because it hands out sweets. The cardboard front panel is the build: paint it a strong colour, cut windows and back them with clear plastic pockets of empty wrappers, then add painted buttons, prices and a coin slot. Hang it from shoulder straps so your arms stay free, and keep it short enough that you can sit on the edge of a chair. All-black clothing underneath makes the machine stand out and hides your body. A neat bun or a bright bob wig, graphic eyeliner in the panel's colour and a fabric bag of wrapped candy let you "dispense" a treat whenever someone calls a number.
3. Garden Gnome On Vacation Costume
What does a garden gnome wear on holiday? A bright shirt, knee-length shorts, striped socks, walking sandals and the pointed red felt hat, which should be lined or stiffened with interfacing so the tip stays up instead of folding over by the second hour. A white costume beard on elastic slips down to your neck when you eat, which you'll want. A blue vest keeps the classic gnome colours, while sunglasses and a floral camera strap say vacation. Rosy blush across the cheeks and nose finishes the face. Carry a map, a light camera or a tiny suitcase with pretend travel stickers, and tuck a few fabric flowers into the hat band as if the gnome packed a bit of garden.
4. Moonlight Gardener Costume
Silver against charcoal gives this gardener a soft, moonlit feel. Charcoal overalls over a silver blouse or long-sleeved top are the base, with felt crescent moons, stars and pale flowers on the pockets. Silver ankle boots or grey sneakers keep it practical. Loose waves threaded with silver ribbon, or a long white-grey wig, suit the palette. Pearly shadow, a few star freckles and a cool-toned highlighter finish the face. I'd always choose paper seed packets over glitter here; glitter sheds onto everyone you hug and turns up for weeks. A metallic watering can of white artificial flowers and an apron holding "Moonflowers" packets tell the story.
5. Lost Sock Detective Costume
Everyone has lost a sock, which is why this joke works so quickly. A tan trench coat over a white shirt, plaid trousers and brown lace-ups make the detective, and clean odd socks pinned across the coat are the "evidence". Use small safety pins rather than glue so the coat survives. A detective hat, a big magnifying glass and a notebook of silly clues about the missing pairs come next. Hair tucked under the hat or left a bit messy both suit the role; neutral makeup with strong brows gives you the focused frown. A cardboard washing-machine dial on a crossbody bag, and one striped sock labelled "Prime Suspect", land the joke without a word of explanation.
6. Midnight Snack Costume
Sleepwear is the most comfortable costume base there is, and this one leans right into it. Navy pyjamas with felt stars, a soft robe, fuzzy slippers and a sleep mask pushed up on your forehead set the scene. Fuzzy slippers are slippery on hard floors and useless on a wet street, so if you'll be outside, swap in soft sneakers. Light cardboard cookies, crackers and cereal shapes go in the robe pockets. Loose messy waves, or a couple of soft rollers left in, suit the hour. Fresh makeup with a silver star beside one eye is enough. Carry a painted plastic cereal bowl of foam cereal pieces, and wear a clock necklace stuck at midnight.
7. Library Ghost Costume
A ghost who never left the reading room, styled softly rather than scary. A grey cardigan over a high-neck white blouse, a long pleated skirt or straight trousers, pale tights and grey loafers give the vintage look. Dust the clothes lightly with white fabric chalk to fade them. Test the chalk on an inside seam first, because some fabrics hold it longer than you'd want. Grey or white hair in a loose bun and round glasses on a chain set the age. Pale makeup with silver shadow and soft brows look ghostly without fake wounds. Carry a few light faux books with funny haunted-library titles, a clear bookmark garland and a sign reading "Overdue Since Forever".
8. Human Terrarium Costume
The trick is getting greenery onto a clear structure that doesn't swamp you. Forest-green leggings, a matching fitted top and green sneakers or ankle boots form the base. A light transparent cape, or a clear umbrella-style frame resting on your shoulders, carries artificial moss, fabric mushrooms, vines and paper butterflies. Keep it all well behind your face; moss sheds tiny bits that end up in your eyes and drinks. Braid in small faux leaves or wear a moss-green wig. Earthy green shadow, rosy cheeks and a painted vine at the temples finish it. A plant mister with plain water and a cardboard "Low Maintenance" label give people the joke.
9. Cloud Collector Costume
Polyester filling makes the fluffiest clouds, but it pulls apart into wisps, so stitch each cluster to its base with a few loose tacks rather than gluing it. Fix clusters to a light backpack, a hat and a butterfly-style net. Pale blue coveralls, or a blue shirt and relaxed trousers, with white sneakers and cloud-print socks keep the sky theme going. A fluffy ponytail or a short white wig with pale blue clips suits it. White and blue shadow blended across the lids, with a few silver dots, finish the face. Carry clear plastic jars of cotton clouds labelled "Morning Fog" and "Rain Cloud", with secure lids; glass jars and a crowded party don't mix.
10. Disco Houseplant Costume
A houseplant at the disco: a green jumpsuit, a metallic belt, silver platform sneakers and leaf-shaped cuffs. The flowerpot round the waist is the key piece. Make it from flexible foam rather than cardboard if you'll be dancing, because foam squashes and springs back when you bump into things. Leave enough room inside to take a full stride. Broad fabric leaves go on a headband and the shoulders, with small mirrored squares on a few of them to catch the light. A full curly shape, your own or a bright green curly wig, glossy green eyes with silver and warm pink blush finish it. A tiny mirrored watering can or a battery mini spotlight makes a fun prop.
11. Delivery From The Future Costume
A courier from another century needs a uniform that looks used, not shiny-new. Start with a silver utility jumpsuit, or a metallic jacket with grey cargo trousers, then add reflective tape, holographic patches, fingerless gloves and white high-tops. A sleek high ponytail, a sculpted short style or a silver bob wig all suit it. Geometric liner and a small metallic accent on each cheek finish the face. The parcel carries the joke: cover a light box with made-up planet labels, strange barcodes and a big "Express Across Time" stamp. A visor cut from translucent craft plastic adds the future without hiding your face. Battery light strips on a structured crossbody bag finish it, with the battery pack tucked inside the bag.
12. Walking Art Supply Box Costume
Bright overalls do most of the work, so this is a quick one. A white T-shirt, overalls, striped socks and canvas sneakers painted with fabric paint form the base. A shallow cardboard box round the waist holds oversized foam pencils, brushes, crayons and rulers. Make every piece soft and glue it down well, since anything loose ends up on the floor the first time you lean over. Pigtails with multicoloured ribbons or a rainbow bob wig, colourful liner and tiny painted dots across the cheeks keep it playful. Carry a cardboard artist's palette and add a big removable "Creative Emergency Kit" label to the box.
13. Reverse Mermaid Costume
The joke is the mermaid turned upside down, and you can play it two ways. The fuller version is a shimmering blue top and turquoise trousers, with soft fabric fish details at the shoulders and a drawing of human legs on a fin-shaped overskirt. The simpler one is a blue fish hood with skin-tone leggings and ordinary sneakers, which reads faster and lets you walk normally, so it's the version I'd steer most people towards. Visible hair in damp-looking waves, aqua shadow, pearl accents and rosy cheeks finish the face. Carry a shell-shaped bag or an "Ocean Fashion Experiment" sign, and if you add fin decorations to flat blue shoes, make them removable.
14. Museum Audio Guide Costume
Precise, quiet styling sells this one, so resist adding colour. Black trousers, a black turtleneck, polished loafers and a lanyard with a made-up museum badge are the uniform. A large foam headphone shape rests round your shoulders, and numbered exhibit buttons go on the shirt. Sleek hair, or a neat black bob wig, and understated makeup with precise liner fit the role. Carry a light control panel with play, pause, language and volume symbols. A cardboard frame around your upper body labelled "Exhibit 31: Person Attending a Party" is the best line in the outfit. Have a few short funny descriptions ready for when guests press a button, because they will.
15. Solar System Tourist Costume
A tourist on a tour of the planets, dressed in holiday clothes. A bright vacation shirt, shorts or trousers, supportive sneakers and a belt bag covered in paper planet patches are the base. The hat is the fun bit: small foam planets on short flexible wires around a wide brim. Keep the wires short and tip each end with a foam ball so nothing pokes anyone at eye level. Braids, a ponytail or a short purple wig all suit it. Shimmering navy shadow and tiny star freckles finish the face. Carry a folded "Solar System Travel Guide", a camera and postcards from made-up planetary resorts. A light cardboard oxygen tank on a backpack and silver-framed sunglasses complete the visitor.
16. Butterfly Postal Worker Costume
Butterfly wings on a postal uniform is a sweet idea, and the uniform is what keeps it clear. Blue shorts or trousers, a matching button-front shirt, comfortable black shoes, a small postal cap and a crossbody mailbag make the worker. Large fabric wings in blue, yellow and orange go on the back. Wings and a crossbody strap fight each other, so fit the wings first and run the bag strap over them, not under. A low ponytail or a short blue wig under the cap, wing-shaped liner and soft peach blush suit it. Fill the bag with envelopes addressed to flowers, bees and garden creatures, add antennae to the hat and pin small felt flowers to the pockets.
17. Human Mood Ring Costume
A plain black base lets the big "stone" stand out. A fitted black top, black trousers or a long black skirt and black boots go first. The chest piece is a large circle of iridescent cardboard or colour-shifting cellophane in a silver foam frame. Cellophane crinkles and tears where it bends, so mount it flat on card before you frame it. A sleek ponytail with purple and blue extensions, several cool shadows blended together and glossy highlighter suit the ring. The mood chart is where the humour lives, with shades for "hungry", "ready to dance" and "thinking about snacks". Silver gloves and a jewelled headband pull the ring theme together.
18. Sleepy Alarm Clock Costume
Anyone who hates mornings gets this straight away. Striped pyjamas, a cosy robe, patterned socks and cushioned slippers with nonslip soles are the base; the nonslip part matters on party floors. The clock face is foam board, round, worn over the torso on soft straps, with flexible foam bells above the shoulders and the hands set to some painfully early hour. Deliberately tousled hair or a messy bun wig and minimal makeup with a little pale shadow under the eyes give you the tired look. Carry a pillow and an oversized cardboard snooze button. A battery bell sound is funny once or twice, and then it isn't, so use it sparingly.
19. Farmer From Another Planet Costume
Country workwear meets outer space. Metallic overalls over a neon plaid shirt, silver rain boots or bright work-style sneakers, and foam patches shaped like strange vegetables make the farmer. Spray-painting a straw hat silver works, but do it outdoors the day before so the smell has gone; a vivid green wig under the hat adds the alien. Purple shadow, green freckles and rosy cheeks finish the face. A basket of handmade spiral carrots, spotted pumpkins and star-shaped produce is the prop, with a "Fresh From Orbit" sign to explain it. Iridescent gardening gloves and a toy watering can painted metallic blue complete the farmer.
20. Mobile Lost And Found Costume
This version swaps a vest for a security-style jacket, and every object hangs from a removable loop. Sew or pin small ribbon loops across the jacket first; then a single glove, toy sunglasses, keychains, scarves and odd socks clip on and off. Numbered tags on each item make it look official. Straight trousers and supportive lace-ups suit a long night on your feet. Tidy hair under a simple cap and natural makeup with defined brows keep the attendant believable. A clipboard of funny descriptions for each "lost" item and a small open box labelled "Claim Desk" do the talking, plus a lanyard with a made-up badge. No real keys, nothing valuable and nothing sharp.
21. Daydream Office Worker Costume
Office clothes with your head in the clouds. Tailored trousers, a button-down shirt, loafers and a soft cardigan in light blue or grey make the worker. Felt clouds sit on the shoulders, and small paper thought bubbles rise from a light headband, filled with pictures of beaches, desserts, naps or outer space. Mount the bubbles on thin wire so they bob a little as you move. Start the night with a neat bun and let it loosen around the clouds as the evening goes on. Soft blue shadow and pearly highlighter suit it. Carry a folder labelled "Important Daydreams" and a star-covered mug, and add a tie or scarf printed with tiny clouds.
22. Pocket-Sized Giant Costume
Scale is the joke: a giant with a whole tiny town in their pockets. Roomy overalls, a plaid shirt, sturdy boots and a floppy beanie make the outfit. Big fabric pockets sewn or pinned across the overalls hold miniature trees, foam houses, toy cars and tiny street signs. Fix everything down, because small pieces fall out every time you bend, and the toy cars end up underfoot. Loose braids or a messy wig under the hat, warm blush and a few freckles keep the giant friendly. Carry an oversized foam spoon or a huge paper map. Skip platform shoes; you're already playing big, and flat boots keep you steady.
23. Rainbow Repair Technician Costume
Someone has to fix the sky when a colour goes missing. White coveralls or a utility jumpsuit with removable rainbow stripes and silver reflective tape make the uniform. Ribbon or felt stripes on hook-and-loop dots come off for washing, which white coveralls will need. A colourful tool belt holds foam paint rollers, ribbon spools and cloud patches. White sneakers with rainbow laces, a high ponytail with multicoloured extensions or a short rainbow wig, and bright graphic liner with silver accents suit the job. A clipboard of made-up repairs such as "Replace Missing Blue" and "Polish Cloud Edge", and a sky-blue hard hat, finish it.
24. Tea Bag In Hot Water Costume
A pun on being in trouble, done without any real drinks or breakables. A tan tunic or oversized beige shirt over brown leggings and flat brown boots is the bag. A large translucent pouch round the torso, stuffed lightly with brown tulle, plays the tea leaves; organza or sheer curtain fabric works well for the pouch and costs little secondhand. A long white cord from the shoulder ends in a cardboard "Tea" tag. A smooth bun or a warm brown bob wig, bronze eyes and rosy cheeks suit it. Around the lower half, removable fabric flames or wavy red-and-blue ribbons stand in for the hot water. The worried expression is what makes people laugh, so practise it.
25. Night Shift Sun Costume
A sun clocking in for the night shift is a nice contradiction to wear. A golden-yellow sweatshirt, matching trousers and yellow sneakers make the sun, and a circular ray collar cut from flexible foam frames your face. Keep the rays short and soft so you can hug people and pass through a crowd. A navy work vest with a "Night Shift" badge goes over the top. A messy golden ponytail or a short yellow-orange wig, warm gold shadow, a little shimmer and soft orange blush finish the face. Carry a thermos-style prop, a clipboard and a small crescent-moon coworker badge. Dark blue gloves and star-print socks bring in the night.
26. Memory Collector Costume
This one is sentimental, and you can make it personal without making it complicated. A plum or navy velvet jacket over a cream shirt, dark trousers and lace-up ankle boots give the collector a slightly old-world look. Velvet gets warm indoors, so a cotton shirt underneath is kinder than anything synthetic. A crossbody satchel holds empty envelopes, photo-frame props, ribbon bundles and paper labels for happy imaginary memories. Loose curls, a low bun or a silver-purple wig, lavender eyes and tiny gold dots suit the mood. Clear plastic bottles of coloured paper curls and fairy lights, labelled "First Snow", "Best Joke" or "Summer Afternoon", are the prop. Round glasses and a cardboard pocket watch finish it.
27. Walking Search Bar Costume
A modern idea that works as long as you keep it generic and don't copy any real company's logo. A plain white top, white or light grey trousers and clean sneakers form the base. A long rounded rectangle of white foam board sits across the torso on comfortable straps, with a generic magnifying-glass symbol and a removable strip for funny search phrases. Keep a few spare phrase strips in your bag so you can change the "search" through the night. A sleek ponytail or simple bob and clean makeup with sharp black liner and a touch of silver suit it. Suggestion cards for guests and a headband with a small spinning "loading" symbol add the last laugh.
28. Seasonal Closet Costume
Four seasons on one body needs a plan before you start pinning. Divide a jumpsuit, a dress or a shirt and trousers into four colour zones and give each its own symbols: flowers for spring, felt suns for summer, fabric leaves for fall and soft snowflakes for winter. I'd mark the zones with chalk while you're wearing the outfit, because quarters on a hanger don't land where you expect on a body. Removable shoe decorations carry each zone down to the hem. Four small hair sections tied with matching ribbons, or a multicoloured wig, and pink, gold, copper and silver eye accents follow the pattern. Carry a rotating cardboard calendar, and keep everything flat and bendy so you can sit.
29. Professional Cloud Taster Costume
A crisp uniform makes an absurd job believable. White trousers, a pale blue shirt, a white apron and comfortable white shoes are the taster's kit. Polyester-filling clouds go on the apron pockets and a chef's hat. Neat hair under the hat or a short silver-blue wig, icy blue shadow, pearly cheeks and white graphic liner finish the face. Carry a small tray of firmly attached cotton clouds labelled with flavours such as "Vanilla Sky" and "Blueberry Breeze", plus a clipboard of cloud ratings. Stray fibres near the face make your eyes water, so keep the clouds on the hat back from your forehead and the tray at chest height.
30. Time Traveler With The Wrong Decade Costume
Getting the eras to clash on purpose is harder than it sounds; a random mix just looks like you dressed in the dark. Pick one strong piece from each decade, such as wide-leg disco trousers, a neon windbreaker, a vintage bow tie, modern sneakers and a futuristic metallic belt, and make sure each one is obvious. A small cardboard control panel on the wrist and a clock-covered crossbody bag add the time machine. Style each side of your hair differently, one sleek and one teased. Colourful geometric eye makeup with silver accents suits the chaos. Carry a folded timeline map of funny destination corrections, and add round glasses, patterned socks and a few dead watch faces.
A Pocket Repair Kit for the Night
Handmade costumes get knocked, hugged and sat on, and something always comes loose by mid-evening. I tuck a small zip bag into a pocket or the costume itself, and it saves the night more often than you'd think.
- A strip of safety pins in two sizes, for felt shapes, straps and hems that let go.
- A short roll of clear tape and a few glue dots for card and paper labels.
- A couple of spare labels or signs, since the joke usually lives on a piece of card that gets bent first.
- Bobby pins and a hair tie for hats, headbands and wigs that start to slip.
- Makeup wipes and a cotton bud for smudged eyeliner, painted freckles or a stray dot that ended up on your collar.
Keeping the joke going after the first hour
Interactive costumes like the vending machine, the bulletin-style board or the search bar wear thin if the same gag repeats all night. Bring refills: extra wrapped sweets, fresh phrase strips, a second batch of suggestion cards. It keeps people coming back to you, and you won't spend the last two hours explaining an empty prop.
Your Own Closet Is the Best Starting Point
None of these needs a popular character or expensive specialist pieces. A clear idea, a shape people can read, a tight colour palette and one good prop do the work, and nearly everything else can come from a drawer or a thrift shop. Adjust any of them for your age, your body, the weather and how much you'll be moving. Use soft craft materials, check every attachment, and wear shoes you'd happily stand in for hours. Then add the small personal touches, your own labels, your favourite colours, a joke only your friends will get, because those are the details people remember.
