Halloween is on Saturday, October 31 this year, and if you’re reading this with an empty costume rail and a party invite staring at you, you’re in good company. The good news: some of the most recognisable Halloween looks ever created come from a bedsheet, a black dress, or ten minutes with an eyeliner pencil. These easy DIY halloween costumes need no sewing machine, no craft store run, and no big budget — most are halloween costumes with stuff you already have, plus at most one cheap add-on.

Below are 30+ last minute costume ideas for adults — sorted by how long they actually take (5 minutes, 30 minutes, or about an hour) — with sections for women, men, couples, groups, and even a kids add-on. Almost all of them qualify as cheap last minute halloween costumes under $20; most cost nothing at all. Pick your time budget, raid your closet, and you’re done.

Quick Picks: The 8 Easiest Last-Minute Costumes

Short on reading time? Start here. These are the fastest diy halloween costumes from your closet, ranked by effort:

Before You Start: The 3 Rules of Last-Minute Costumes

Rule 1: Start with what you own. Lay out your black clothes, white clothes, plaid shirts, stripes, and anything orange. Half the costumes on this list are hiding in a normal wardrobe.

Rule 2: One prop sells the whole look. A costume reads instantly when it has a single strong signal — cat ears, a paper crown, a broom, a drawn-on moustache. Spend your effort (and money) on that one item.

Rule 3: Makeup counts as a costume. Eyeliner whiskers, dark lipstick, or white face paint can carry an otherwise plain outfit. If you own makeup, you own a costume shop.

5-Minute Costumes (Seriously — Five Minutes)

These 5 minute halloween costumes are the emergency halloween costume ideas: no sew halloween costumes in the truest sense, assembled faster than a coffee run.

1. Classic Ghost

What you need: A white bedsheet, scissors, black marker or dark makeup.
How to do it: Drape the sheet over your head, mark where your eyes land, take it off and cut two eye holes. Rough up the bottom edge with a few snips so it doesn’t look freshly laundered. Instant, timeless, and genuinely comfortable for a party.

2. Black Cat

What you need: All-black outfit, cat ears (bought cheap or made from cardboard and a headband), black eyeliner.
How to do it: Dress head-to-toe in black. Draw whiskers and a small nose with eyeliner, add the ears, and you’re done. A tail can be a black scarf or belt tucked at the back. This is the most reliable of all easy halloween costumes for women — and it works for anyone.

3. Tourist

What you need: Hawaiian or loud printed shirt, shorts, socks with sandals, sunglasses, a camera or phone on a strap, a hat.
How to do it: Layer everything at once — the comedy comes from commitment. Add a paper map or hold your phone up taking photos of nothing. Works brilliantly as a group or couples look too: matching tourists are funnier than one.

4. Bank Robber

What you need: Black-and-white striped shirt, black trousers, black beanie, a plain tote or pillowcase.
How to do it: Put on the stripes and beanie, then draw a simple “$” on the tote bag with a marker — that’s your swag bag. Add a black eye mask cut from an old t-shirt if you want the full cartoon effect. A staple of last minute halloween costumes for men because every wardrobe has the parts.

5. Pumpkin

What you need: Orange top or dress, green or brown hat/scarf, black face paint or eyeliner, black leggings or trousers.
How to do it: Wear orange top to bottom. Draw a triangle-eyed jack-o’-lantern face on a plain orange t-shirt with a fabric marker, or paint small triangles on your cheeks. A green headband or scarf is the stalk. Cute, unmistakable, zero sewing.

6. Mime

What you need: Striped long-sleeve top, black trousers, white face paint or pale foundation, black eyeliner, optional beret and white gloves.
How to do it: Pale face, exaggerated black brows and lips drawn with liner, then commit to the bit — you’ll be trapped in an invisible box by the food table within the hour. The costume is 50% makeup, 50% performance.

7. Cowboy or Cowgirl

What you need: Plaid shirt, jeans, boots, bandana, a belt with a big buckle, hat if you own one.
How to do it: Tie the bandana at your neck, roll the sleeves, and add a toy sheriff badge made from foil-covered cardboard if you’re feeling crafty. Most wardrobes already contain 90% of this costume.

8. Sleepwalker

What you need: Pyjamas, a dressing gown or blanket, slippers, a teddy bear or pillow.
How to do it: Put on your actual pyjamas, mess up your hair, add half-asleep eyeliner smudges, and carry the teddy. The joke lands instantly and you are, without question, the most comfortable person at the party. Also a perfect low-effort pick for older kids.

30-Minute Costumes (A Little Effort, Big Payoff)

9. Gothic Schoolgirl Look

What you need: Black dress (ideally with a collar or add a white shirt underneath), two braids, dark makeup, black boots.
How to do it: Centre-part your hair into two tight braids. Keep the makeup pale with dark eyes and a deep lip, and keep your expression gloriously unimpressed. A small cross necklace or choker finishes it. Deadpan delivery all night is mandatory.

10. Vampire

What you need: Black outfit (a blazer or dress works), white face makeup or pale foundation, dark red lipstick, black eyeliner, optional plastic fangs.
How to do it: Go pale, darken the eyes, and draw a thin trickle of fake blood or red lipstick from the corner of your mouth. Slicked-back hair and a high collar (pop a blazer’s collar up) sell the aristocratic angle. Fangs are cheap everywhere this week if you want them.

11. Scarecrow

What you need: Plaid shirt, jeans or dungarees, straw hat or any wide-brim hat, raffia/straw or yellow yarn, face paint.
How to do it: Stuff straw or yarn strands into your cuffs, collar, and pockets so it pokes out. Draw stitched lines across your cheeks and a triangle nose with face paint. A few patches drawn or safety-pinned onto jeans completes the just-left-the-cornfield look.

12. Closet Witch

What you need: Black dress or all-black outfit, pointy hat (bought cheap, or rolled black card into a cone), a broom from your kitchen.
How to do it: The hat and broom do all the work — everything else is just black clothing. Add purple or green eyeshadow and dark lipstick for a modern witch, or a drawn-on wart and wild backcombed hair for the storybook version.

13. Skeleton (Makeup-Led)

What you need: Black outfit, white and black face paint, black eyeliner.
How to do it: Paint your face white, hollow out the eyes with big black circles, add a black nose triangle, and draw vertical lines across your lips for teeth. Even a half-face version (one side skeleton, one side normal) looks impressive and takes half the time. Full step-by-step in the makeup section below.

14. Pirate

What you need: White or striped shirt, black trousers or skirt, red or black bandana, belt, eyeliner, optional foil hook or cardboard sword.
How to do it: Tie the bandana, smudge eyeliner for a weathered look, and draw on a scar or beard stubble. A gold earring (clip-on or a paperclip trick) and a sash made from a scarf at the waist finish it. Talk like a pirate sparingly — your friends will thank you.

15. Chef

What you need: White shirt, apron, a paper or cloth chef’s hat (easy to fold from white paper and tape), a wooden spoon.
How to do it: The hat is the whole costume — there are simple no-sew folded-paper versions that take ten minutes. Carry the spoon, dust a little flour on your cheek, and spend the party near the snacks where you belong.

16. Zombie

What you need: Old clothes you don’t mind ruining, dark eyeshadow or face paint, fake blood or red lipstick.
How to do it: Rip small tears in the clothes (or cut and fray the hems), smudge dark shadow in big circles under your eyes, and add grey-green smears to your skin. Shuffle practice is optional but encouraged. Use clothes already headed for the rag pile — fake blood does not wash out.

17. Secret Agent

What you need: Black suit or dark blazer and trousers, white shirt, sunglasses, a phone earpiece or coiled wire.
How to do it: Suit up, sunglasses on (yes, indoors — that’s the joke), earpiece in, and introduce yourself with a different name to every group. One of the sharpest last minute halloween costumes for men, and it doubles as work-appropriate for office parties with a dress code.

1-Hour Costumes (Maximum Impact)

18. Full-Face Skeleton / Day of the Dead Style

What you need: Full face paint set (white, black, plus colours if going decorative), fine brushes or sponges, black outfit or floral dress.
How to do it: Block out a full white base, then build the eye sockets, nose, and stitched mouth carefully — this is the one-hour part. For the decorative version, add coloured flower petals around the eyes and real or paper flowers in your hair. Photographs incredibly well.

19. Deck of Cards (Group of 4+)

What you need: Large white card or poster board per person, red and black markers, string or ribbon.
How to do it: Each person draws a card face — a big A, K, Q or J with a heart, diamond, club or spade — on their board and hangs it front and back with ribbon like a sandwich board. As a group you’re unbeatable; individually you’re still clearly a playing card. Cheap, funny, and flat-pack for transport.

20. Retro Game Blocks (Group of 4)

What you need: Four large cardboard boxes, coloured paint or paper (four bright colours), black marker or tape.
How to do it: Cover each box in a different colour and outline the block squares with marker or tape to make chunky pixel-style game pieces — an L, a T, a square, and a straight line. Cut arm and head holes. As a group, keep “falling” into place together all night for photos.

21. Gothic Couple (Couples)

What you need: One black suit or dark formal outfit, one long black dress, pale makeup for both, dark lipstick.
How to do it: This is the vampire’s elegant cousin: full formal wear, everything black, both of you pale and severe. He slicks his hair; she adds a choker and gloves. Carry yourselves like you own a haunted mansion and let everyone else figure out the rest.

22. Salt and Pepper (Couples)

What you need: One all-white outfit, one all-black outfit, two sheets of card, markers, tape or safety pins.
How to do it: Draw a big “S” on white card for the person in white and a “P” on black card (in white marker or white paper letters) for the person in black. Pin them on. Add grey/silver caps as shaker lids if you have them. Simple, instantly readable, endlessly photographable.

23. Peanut Butter and Jelly (Couples)

What you need: One tan/brown outfit, one purple outfit, card and markers for labels.
How to do it: Wear your colour head-to-toe and pin on a hand-drawn label — “PB” in a brown circle, “J” in a purple one. It takes twenty minutes if you dawdle, and couples-costume contests love it because it’s clear from across the room.

24. Tourist Couple, Deluxe Edition (Couples)

What you need: Two loud shirts, two hats, sunglasses, a paper map, sticker “luggage tags” on your bags.
How to do it: The five-minute tourist, doubled and upgraded: matching shirts if you can manage it, socks with sandals for both, and a shared bit — photographing everything, consulting the map upside down. Doubling a simple costume almost always beats one complicated one.

2026 Pop-Culture Quickies

Fresh references make a closet costume feel current. These four borrow the year’s most recognisable looks — all achievable with office wear and one prop.

25. Severance-Style Office Worker

What you need: Office outfit (turtleneck or shirt and trousers), a lanyard with a blank ID badge, a tote or briefcase.
How to do it: Dress in muted office neutrals, clip on the badge, and adopt a pleasantly blank expression. Carry a folder labelled with a made-up department name. Fans will get it instantly; everyone else just sees an eerily committed office worker.

26. Error 404: Costume Not Found

What you need: Plain white or black t-shirt, a sheet of paper or card, marker, safety pins.
How to do it: Write “ERROR 404 — COSTUME NOT FOUND” on the card and pin it to your chest. That’s it. It’s the funniest zero-effort costume of the year, endlessly office-appropriate, and the single most-photographed joke at any party.

27. 2016 Throwback

What you need: Ripped skinny jeans, a choker, a bomber or denim jacket, heavy brows, dark or matte lipstick.
How to do it: Rebuild the full mid-2010s uniform: choker tight, brows bold, jacket over a plain tee, and a flower-crown filter pose for every photo. Nostalgia is a costume now — lean into it.

28. Social Media Influencer

What you need: Your nicest casual outfit, sunglasses, a phone on a selfie stick or small ring light.
How to do it: Carry the ring light, narrate your evening to an imaginary audience (“hey guys, welcome back”), and ask strangers to rate your outfit haul. The costume is the performance; the props just get you recognised faster.

Funny Halloween Costumes: Puns & Visual Gags

If you’d rather get a laugh than a scare, these funny last minute halloween costumes are pure wordplay — each one takes under 15 minutes and costs almost nothing.

• Cereal Killer — Pin empty mini cereal boxes to a plain shirt, carry a plastic spoon or toy knife, and look vaguely suspicious. The groan it earns is the point.
• Identity Thief — Cover a shirt with “Hello, my name is…” stickers, each filled in with a different name. Every introduction is a new identity.
• Ceiling Fan — Wear a plain top, hold homemade pom-poms or a foam finger, and carry a sign reading “GO CEILING!” You are the ceiling’s number one fan.
• Deviled Egg — Wear all white or cream with a yellow circle pinned to your front (the yolk), and add devil horns. Breakfast, but make it evil.
• Bread Winner — Wear a sports medal (or a foil one you make) and carry a loaf of bread everywhere like a trophy. Hold it up for photos.
• Formal Apology — Put on your smartest shirt, jacket, or dress, and pin on a sign that simply says “I’M SORRY.” Formal wear, formal apology.

Makeup Does the Heavy Lifting: 3 Mini Guides

A basic face-paint set or your existing makeup bag can produce a full costume on its own. These three makeup-led looks are the highest-impact emergency halloween costume ideas on this page.

Skeleton (about 25–30 minutes):
1. Sponge white paint or pale foundation over the whole face, leaving the eye sockets bare.
2. Fill each socket with a large black circle extending above and below the eye.
3. Paint a black triangle on the nose tip.
4. Draw vertical lines across your closed lips, extending slightly past the corners, for teeth.
5. Optional: shade the cheek hollows with grey or black smudges. Wear black.

Black cat (about 10 minutes):
1. With black eyeliner, draw a small filled triangle on the tip of your nose.
2. Add three whisker lines on each cheek, sweeping outward.
3. Line your upper lids with a flick for a feline eye.
4. Add ears (headband or cardboard) and wear all black.

Deer / fawn (about 20 minutes):
1. Warm brown foundation or bronzer across the cheeks, forehead edges, and jaw.
2. White or cream paint spots dotted along the cheekbones and forehead.
3. Black paint or liner on the nose tip, with a short line down to the lip.
4. White liner on the lower waterline to widen the eyes; add ears or antlers on a headband if you have them.

Kids Add-On: 4 Mini Costumes for Children

Short a costume for a small person too? These scale the same closet-first logic down:

• Towel-cape superhero — A towel or pillowcase clipped at the neck with a clothespin, a paper emblem pinned to the chest, and a name they invent themselves.
• Little ghost — The classic sheet costume, sized down: use a white pillowcase with eye holes for toddlers (shorter, less tripping) and supervise little ones closely.
• Pirate kid — Striped t-shirt, a bandana, an eyeliner scar or moustache, and a cardboard sword covered in foil.
• Pumpkin baby/toddler — An orange top or onesie with a felt or paper jack-o’-lantern face stuck on with double-sided tape, plus a green hat or headband stalk.

Can You Still Order a Costume in Time?

Honest answer: maybe — but check the delivery date, not the delivery promise. As Halloween falls on Saturday, October 31 this year, standard shipping cut-offs at most big retailers have effectively passed by mid-week; what remains is next-day/express delivery and same-day click-and-collect. Practical rules for the final days:

• Order by Wednesday, October 28 if you’re relying on express delivery, and only if the checkout shows a delivery date of October 30 or earlier (expected — cut-offs vary by retailer and postcode, so the date at checkout is the only number that counts).
• Click-and-collect beats delivery this late: if the store near you has it in stock today, reserve it today.
• Discount and grocery stores stock costumes into the final week, but sizes thin out fast — go early in the day.
• If it won’t arrive by Friday, commit to the closet. Every idea on this page is faster than a refund queue, and a costume you’re wearing beats a better one in a delivery van.

Budget Notes: What This Actually Costs

Most of these ideas cost nothing beyond what’s in your closet, and every paid item mentioned — cat ears, plastic fangs, a basic face-paint set, poster board — is the kind of thing discount and dollar stores stock heavily in October. A few honest tips:

• Face paint beats masks. One small face-paint set can produce the cat, skeleton, vampire, mime, and scarecrow looks — five costumes from a single cheap purchase, and it packs away for next year.
• Buy the one hero prop only. Ears OR a hat OR fangs. Costumes fail financially when you buy every accessory; they succeed visually with just one strong signal anyway.
• Cardboard is free. Ask a store for a large box before buying poster board — appliance and delivery boxes make perfect playing cards and game blocks.
• Check charity/thrift shops for the base layer. A black blazer, a plaid shirt, or a white sheet bought second-hand costs very little and can go back to the donation pile in November.

Quick Fixes for Common Last-Minute Problems

“I have no black clothes.” Go ghost (white sheet), tourist (loudest colours you own), pumpkin (anything orange), or chef (white shirt). Four of the best looks on this list need zero black.

“I can’t do makeup.” The ghost, bank robber, and deck-of-cards costumes need none at all. For the cat, a friend with a steady hand and an eyeliner pencil is the traditional solution.

“It’s going to be cold.” Choose costumes that layer: the scarecrow (flannel and jeans), tourist (add a jacket — tourists are never dressed for the weather anyway), or ghost (a full outfit fits under the sheet). Skeleton makeup over warm black layers works too.

“I need a work-appropriate costume.” Cat ears plus normal black clothes, the tourist, and the chef all pass office rules — nothing scary, nothing covering your face, nothing you’d regret in the company photo.

Frequently Asked Questions

What is the easiest last-minute Halloween costume?
The classic ghost and the black cat tie for first place. The ghost is one sheet and two eye holes; the cat is black clothes, ears, and eyeliner whiskers. Both take about five minutes and both are instantly recognisable.

What can I wear for Halloween with no costume at all?
Build the costume from signals, not garments: eyeliner whiskers and ears turn normal black clothes into a cat, and a paper sign turns a plain t-shirt into Error 404 or a Formal Apology. If you truly change nothing, a drawn-on moustache, fake scar, or vampire-pale makeup over your regular outfit still reads as a costume at a party.

How can I make a costume in 5 minutes?
Pick from the 5-minute section: ghost (sheet plus eye holes), bank robber (stripes, beanie, marked tote), tourist (loud shirt, sunglasses, hat), or pumpkin (orange outfit plus face paint triangles). Lay everything out before you start changing — assembly order is where the five minutes go.

What are good last-minute costumes for couples?
Salt and pepper, peanut butter and jelly, the gothic couple, and the tourist couple all come together in under an hour from normal clothes, and all of them read clearly in photos. The bank robber duo (two striped shirts) is the fastest couples option of all.

Can I still order a costume online and get it before October 31?
Possibly, with express or next-day delivery ordered by around Wednesday, October 28 — but only trust the delivery date shown at checkout, not the shipping speed’s name (expected — cut-offs vary by retailer). Same-day click-and-collect is the safer bet this late, and every closet costume on this page is faster still.

What is a good last-minute costume for work or the office?
The black cat (ears plus normal black clothes), the tourist, the chef, the secret agent, and Error 404 all pass typical office rules: nothing gory, nothing covering your face, and nothing you’ll regret in the company photo. The secret agent has the bonus of looking deliberate in meetings.

Ready for Halloween Night

However much time you have — five minutes or a full hour — there’s a costume on this list with your name on it. Pick by the clock, stick to the one-prop rule, and spend the time you saved on the fun parts: the party, the trick-or-treat route, and the photos.
