Left it until the last minute? You can still put together a costume that looks good, costs little, and comes mostly from things you already own. DIY has one big advantage over a ready-made costume: you can match it to your own idea, your group, and your budget.
Halloween is a big spending season: the National Retail Federation expects U.S. consumers to spend $13.5 billion this year, up from last year’s record $13.1 billion (NRF, September 2026). DIY is one way to enjoy it without adding to that total.
This guide covers 20 Halloween costume ideas for solo wearers, couples, groups of three, and kids. Each one includes a time estimate and simple steps. You’ll also find five makeup looks you can finish in 5 to 20 minutes, a planning method that works for any costume, and safety tips.
A note for founders, CTOs, and product teams: this Halloween, GMTA Software Solutions is offering 40% off development costs on mobile app, custom software, AI, AI agent, MVP, web, and SaaS projects that kick off between October 1 and November 15, 2026. Mobile app projects also include 6 months of free maintenance. The details are at the end of this guide, or you can go straight to the offer β.
How to Plan a Last-Minute Costume in an Afternoon
Good last-minute costumes follow the same logic. Work through these steps before you buy anything.
- Start with what you own. Black clothing is the base of many DIY costumes: witch, cat, skeleton, Wednesday Addams, vampire. Lay out your clothes before you look at ideas, and you’ll often find half a costume already.
- Pick one recognizable signal. People read a costume in about two seconds. A pointed hat says witch, a magnifying glass says detective, and white bones on black say skeleton. Get that one signal right and keep everything else simple.
- Buy only the missing piece. Thrift stores, dollar stores, and craft aisles cover most gaps. Set a cap before you shop so a “quick” costume doesn’t become an expensive one.
- Test it, then sit down in it. A costume that looks great standing but can’t sit, eat, or hold a drink won’t last a party. Check that you can move, see, and breathe comfortably.
- Keep a repair kit. Safety pins, double-sided tape, and a small glue stick fix most problems mid-party.
Budget and Materials: What Most DIY Costumes Need
| Item | Used for | Where to get it |
| Black clothing | Witch, cat, skeleton, Wednesday, vampire | Your closet |
| Felt and fabric scraps | Wings, ears, frosting, patches | Craft store, old clothes |
| Cardboard | Wings, cans, props, hats | Delivery boxes |
| Face paint or eyeliner | Cat, skeleton, zombie | Drugstore, costume shop |
| Safety pins and fabric tape | Holding everything together | Craft aisle |
| Headbands | Ears, horns, halos, hats | Dollar store |
| Tissue paper and tulle | Popcorn, cotton candy, butterfly | Craft store |
Budget tip: thrift stores are picked over in early October. Check them early in the week, and ask friends and family what they’d lend you before buying anything.
20 DIY Halloween Costumes You Can Make Today
Times and costs are rough estimates for someone starting with basic supplies at home.
Couples and duos
Angel and devil
Time: 30 minutes Β· Cost: low
A classic pair where one partner is good and the other is mischievous. One wears a white halo, made from a headband and wire or a glittered ring. The other wears black or red with horns on a headband. Cut wings from cardboard and cover them in white fabric or feathers for the angel, and in black or red fabric for the devil. Add a pitchfork made from a dowel and cardboard for the devil. The contrast reads instantly in photos.
Barbie and Ken
Time: 20 minutes Β· Cost: low
Bright pink and denim from your existing wardrobe do most of the work. Barbie: a pink top or dress, white sunglasses, and a bold accessory. Ken: a denim or pastel shirt, a fun belt, and confident posing. Style and attitude carry this costume more than props do. It also works for a group of three with an extra character.
Skeleton couple
Β Time: 45 minutes Β· Cost: low
Start with black long-sleeved tops and leggings. Apply white tape, felt strips, or fabric paint in a rib, spine, and arm-bone pattern. Glow tape or LED strip lights under the bones make the look stand out in low light. Keep the wires tucked away and the battery pack in a pocket. Finish with skeleton face paint (see makeup look #3).
Rosie the Riveter
Β Time: 15 minutes Β· Cost: low
A symbol of women’s empowerment and a very quick costume. Wear a denim or chambray button-up with the sleeves rolled, high-waisted trousers or jeans, and a red polka-dot bandana tied on top of your head. Add red lipstick and a flexed-arm pose. The pose is part of the costume, so it works well for photos. For a duo, pair it with a wartime factory-worker partner.
Groups of three or more
Milkshake flavors
Time: 1 hour Β· Cost: low to moderate
Each person becomes a different flavor: strawberry in pink, chocolate in brown, vanilla in cream. Make the whipped-cream hat from batting or stuffed fabric, and add a red pom-pom cherry on top. For the base, a paper-cup shape from cardboard or a colored outfit works. Give each person an angry expression for the spooky twist. This one suits kids as well as adults.
Leopard and the jungle pack
Time: 45 minutes Β· Cost: low
Start with the leopard, using a yellow or tan top, brown or black spots cut from felt and glued on, ears on a headband, and a tail from a stuffed stocking. Then let the rest of the group choose other jungle animals: lion, bear, or snake. Everyone can use the same materials in different colors, so the group looks coordinated.
Popcorn
Time: 45 minutes Β· Cost: very low
Cut tissue paper into squares, round the corners, and pin them onto a white or cream outfit so they look like kernels. Add a red-and-white striped paper cup as a hat or a striped shirt for the box. Pair it with friends as candy and soda for a snack-bar trio. Tissue paper is flammable, so keep it away from candles and jack-o’-lanterns.
Balloon darts
Time: 1 hour Β· Cost: low
A funny carnival costume. Attach balloons to a cardboard board worn over the front, hold a few darts made from cardboard or foam, and add clown makeup and a bright wig if you like. For a group, others can dress as carnival-game workers or prizes. Use foam or paper darts, not real ones, and inflate the balloons close to the party so they don’t sag.
Solo classics
Witch
Time: 15 minutes Β· Cost: low
A black dress, a pointed hat, and a broom. Add striped or patterned tights and layer a torn cape or shawl on top. For a vintage look, keep the colors dark and add a small bottle “potion” belt. A witch adapts to almost any style: glamorous, scary, or funny.
Wednesday Addams
Time: 20 minutes Β· Cost: low
A plain black dress, a white collar cut from paper or fabric, two tight braids, and a deadpan expression. Add black tights and simple black boots. Pale foundation and a dark lip complete the look. It’s recognizable, affordable, and works for adults and kids.
Nancy Drew
Time: 20 minutes Β· Cost: low
Style a tailored blouse, blazer, and skirt, then add a cable-knit sweater for a classic investigator look. The props make the character: a flashlight, a magnifying glass, and a small notebook. Carry a vintage-style satchel if you have one.
Black cat
Time: 10 minutes Β· Cost: very low
Black clothes, cat ears on a headband, a tail pinned at the back, and eyeliner whiskers. It’s one of the fastest costumes to assemble and one of the easiest to wear all night. Add glitter or colored eyeliner if you want to dress it up.
Zombie
Time: 45 minutes Β· Cost: low
Tear old clothes and rub them with dirt or coffee grounds for a decayed look. Apply gray-green face paint and dark shadow under the eyes and cheekbones. For fake blood, mix corn syrup with red food coloring, or use red food coloring, pomegranate juice, or ketchup. Test it on the fabric first, since food coloring can stain. Practice a slow, stiff walk, because acting is the finishing touch.
Skeleton (with glow effects)
Time: 45 minutes Β· Cost: low
The classic costume for October 31. Start with black clothes and add white bones from tape, felt, or fabric paint. Attach LED strip lights or glow tape for a 3D effect in dim rooms. Finish with skull makeup or a skull mask. Battery-powered LEDs are safer than anything with heat.
Airhead
Time: 1 to 2 hours Β· Cost: low
Build an oversized head from a large cardboard box or foam: a giant pumpkin, a haunted-house hat, or a huge scary dragon mask. Paint or cover it in fabric and cut an eye slot or a mesh window so you can see. Keep it lightweight and check your peripheral vision before walking around. This costume gets attention wherever you go.
Kids and toddlers
Pac-Man
Time: 30 minutes Β· Cost: low
A yellow shirt or sweatshirt with a black wedge cut or drawn as the mouth, plus dots pinned along the sleeve. For a group, add friends in ghost sheets with cut-out eyes. It’s simple and inexpensive, and it works with black leggings and a sheet of plain cloth.
Cotton candy
Time: 45 minutes Β· Cost: low
Pastel tulle or polyester batting shaped into a cloud around a plain base outfit, with a paper cone as a hat. It’s a popular baby and toddler costume. Avoid attaching real candy for toddlers, since it can be a choking hazard, and keep the fabric away from open flames.
Butterfly
Time: 30 minutes Β· Cost: low
A black top and bottom, tie-on wings, and light makeup. Make wings from felt, cardboard, or fabric stretched over wire, and decorate them with paint or glitter. Add antennae on a headband. It removes the need for complicated DIY and suits a kids’ party theme.
Donut
Time: 1 hour Β· Cost: low
A round pool noodle or felt-covered tube worn around the waist, with pink or chocolate felt “frosting” and sprinkles cut from colored paper. It fits the trick-or-treat theme. Keep it lightweight and easy to sit in, and make sure a child can walk up stairs while wearing it.
Gumball machine
Time: 1 hour Β· Cost: low
A clear or colored dome on the top, made from a clear balloon, plastic bowl, or a headband with colorful pom-poms, and a red or blue base shirt. You can customize it in many ways: a robot-style version for kids, or gumball-print tops for adults. Use pom-poms instead of real gum for younger children.
Bonus, the fastest of all: the cut T-shirt skeleton. Cut a black T-shirt into strips that mimic ribs and arm bones, or paint or tape white bones on it, and wear it over a white long-sleeved shirt. It needs one T-shirt and a pair of scissors.
5 Halloween Makeup Looks
Before you start: use cosmetic-grade face paint or makeup, never craft paint or markers. Patch-test on your inner arm first, especially with kids. Remove everything before sleeping.
1. Easy cat (simple, about 5 minutes)
- Draw a wing at the outer corner of each eye with black eyeliner, extending upward.
- Color the tip of the nose black.
- Draw three whiskers on each cheek, angled slightly upward.
- Add cat ears on a headband.
2. Vampire glam (moderate, about 15 minutes)
- Start with a pale foundation or setting powder.
- Add deep red or burgundy lipstick with slightly sharpened edges.
- Blend dark shadow under the cheekbones and around the eyes.
- Add fake blood at the corner of the mouth, applied last.
- The look can be subtle or dramatic. Use Halloween face paint if you want a stronger effect.
3. Skeleton face (spooky, about 20 minutes)
- Apply white face paint over the whole face and let it dry.
- Paint the eye sockets black, blending outward.
- Paint the nose as an inverted black heart.
- Draw vertical lines over the lips for teeth.
- Set the paint with translucent powder so it doesn’t smudge.
4. Scarecrow (fun and creepy, about 15 minutes)
- Apply a warm tan or beige base.
- Draw stitch lines with black eyeliner on the cheeks and around the mouth.
- Add dark, rough texture around the eyes and freckles with brown shadow.
- Add a patched hat and straw at the collar for detail.
5. Zombie apocalypse (extreme, about 20 minutes)
- Apply a gray-green base over the face and neck.
- Add dark purple and black shadow around the eyes and hollows of the cheeks.
- Create wounds with scar wax or liquid latex and fake blood.
- Stipple a little brown and black over the whole face for a decayed texture.
Safety Tips for DIY Costumes
- Make sure you can see. Masks and big heads need eye openings, and check your peripheral vision.
- Add visibility for trick-or-treating. Reflective tape or a small light helps drivers see kids after dark.
- Watch flammable materials. Tissue paper, tulle, and cotton batting burn easily. Keep them away from candles and jack-o’-lanterns.
- Choose comfortable footwear. Costumes with long hems or props should not cause trips.
- Skip toxic products. Use cosmetic-grade makeup only, and patch-test first.
- Keep small parts away from toddlers. Buttons, beads, and candy can be choking hazards.
Coordinating a Group Costume
- A group costume works best when it has one clear theme and a role for everyone.
- Choose a theme first, such as snacks, jungle animals, or carnival games.
- Give each person a distinct role so the group doesn’t look identical.
- Share materials. Buy one roll of tape, one bag of felt, and one set of paint, and split the cost.
- Match colors or shapes, not exact outfits, so everyone can use what they own.
- Agree on a deadline so no one is still gluing at the party door.
