Last-Minute DIY Halloween Costumes From Things You Already Own

Picture a parent standing in front of an open hallway closet at 8 p.m. on a Thursday. The class party is tomorrow, Halloween is Saturday, and the costume that was “definitely fine” no longer fits.

The stores are picked over. The budget is spoken for. What’s left is a closet, a junk drawer and a recycling bin.

Good news: that is usually enough.

When is Halloween 2026, and how much time do you have?

Halloween falls on a Saturday this year, Saturday, Oct. 31, 2026. That means many school parties and office contests land on Friday, Oct. 30, and trick-or-treating can run into a relaxed weekend evening.

If you are reading this the week of Oct. 21, you have roughly ten days. That is plenty for any costume on this list. Most take an evening, and a few take less than an hour.

You would not be alone in reaching for the closet. The National Retail Federation expects Halloween spending to reach $13.5 billion this year, with 71% of shoppers planning to spend a combined $4.4 billion on costumes. Average spending is expected to be $115.14 per person. A homemade costume keeps more of that money in your pocket.

What are the most popular Halloween costumes in 2026?

NRF’s annual survey, conducted by Prosper Insights & Analytics with 7,889 consumers from Sept. 1 to 9, lists the top adult costumes as witch, vampire, Batman, Spider-Man and ghost. For kids, the top five are Spider-Man, a generic superhero, princess, witch and ghost. For pets, it’s a pumpkin, a hot dog and a ghost.

Look at that list again. Witch, vampire, ghost, superhero and princess are classics precisely because they are easy to build from ordinary clothes. You do not need a licensed costume to be recognizable.

The same survey found online search is still the top source of costume ideas at 32%, down from 37% last year. Sometimes the best idea is the one hanging in your own closet.

Which DIY costumes can you make tonight from things at home?

Each of these starts with a base outfit and adds one or two signature pieces. That is the whole trick.

Witch

Wear black or dark purple clothes. Roll a sheet of black poster board into a cone, tape the seam, and set it on a ring cut from a second piece for the brim. Borrow a broom from the garage. A striped pair of socks or tights finishes it.

Vampire

Dark pants, a white button-down shirt and a dark tablecloth or old curtain worn as a cape. Cut a tall collar from a cereal box, cover it with black paper, and tape it inside the cape at the neckline. A little face powder and dark lipstick handle the rest.

Ghost (the safer version)

The classic sheet ghost is fun but can block vision. Instead, dress head to toe in white and use white face makeup with gray around the eyes. If you do use a sheet, hem it above the ankles and cut eye holes wide enough to see your feet.

Superhero

A solid T-shirt becomes a hero shirt with an emblem cut from felt or construction paper and attached with safety pins or fabric tape. A pillowcase makes a cape. Pin it at the shoulders instead of knotting it at the throat. Invent the hero’s name together, which kids tend to love more than any store costume.

Paper princess or prince

Any dressy outfit works. The crown is the star: cut a zigzag band from a cereal box, cover it with foil or gold paper, and glue on bottle caps or buttons as jewels.

Cardboard robot

A shipping box with arm and head holes, wrapped in foil, becomes a robot body. Glue on bottle caps for dials and draw a control panel with a marker. Keep the head uncovered and wear a silver knit cap so the wearer can see and move freely.

Scarecrow

Flannel shirt, jeans, a straw or bucket hat, and a few strands of raffia or twine poking out of the cuffs. Draw stitched lines at the corners of the mouth with an eyeliner pencil.

Pumpkin, for kids or pets

An orange sweatshirt with a black construction-paper face pinned on front, and a green knit cap as the stem. For a dog, a simple orange bandana with a felt jack-o’-lantern face is plenty. Many pets dislike full costumes, so keep it light and remove it if your pet seems stressed.

If you have a sewing machine and a free evening, a few straight seams turn any of these into something sturdier. Our guide to easy sewing projects for kids covers the basic stitches, and folded paper bats from our beginner origami folding guide make a quick accessory for the witch or vampire.

How do you make a homemade costume safe for trick-or-treating?

Homemade costumes skip the safety labels that store-bought ones carry, so the checks fall to you. The U.S. Food and Drug Administration’s Halloween safety guidance is short and practical:

• Fabric: If you make your costume, the FDA suggests flame-resistant fabrics such as polyester or nylon.
• Visibility: Wear bright, reflective costumes or add strips of reflective tape so drivers can see you.
• Length: Make sure costumes are not so long that the wearer could trip.
• Vision: Choose makeup and hats over masks that can block vision.
• Makeup: Test makeup 24 to 48 hours ahead on a small patch of the wearer’s arm and watch for redness or irritation.
• Contact lenses: Don’t wear decorative colored lenses unless an eye care professional has fitted you and explained how to use them.

A few common-sense additions: keep capes and scarves loose at the neck, avoid long trailing pieces near candles or jack-o’-lanterns, and tuck a small flashlight into the costume. For children, a grown-up should check every costume in the dark before heading out.

What should you do this week to be ready by Saturday?

1. Tonight: Pick the costume and pull the base outfit from the closet.
2. Midweek: Make the signature piece, whether that’s the hat, collar, crown or box.
3. Thursday: Patch-test any face makeup so you have the full 24 to 48 hours to watch for a reaction.
4. Friday: Add reflective tape, check hem lengths, and do a test walk.
5. Saturday, Oct. 31: Wear it, take a photo, and enjoy the evening.

Back at that hallway closet, the answer was hiding on the top shelf: a black sweater, a roll of poster board, and a broom from the garage. By Saturday night, the costume that cost nothing was the one the neighbors asked about.

Frequently asked questions

What is the easiest last-minute Halloween costume?

A witch or vampire is usually easiest because both start with dark clothes most people already own. Add one signature piece, such as a poster-board hat or a cardboard collar, and the costume reads clearly from across the street.

Can I make a Halloween costume with no sewing?

Yes. Safety pins, fabric tape, glue and staples handle almost every costume on this list. Sewing makes a costume sturdier for repeat wear, but it is not required for one night.

What should I use to make a homemade costume more visible at night?

The FDA recommends bright, reflective costumes or strips of reflective tape. Adding tape to the back of a cape, the hem of a sheet, or the sides of a treat bag helps drivers see trick-or-treaters.

Is it safe to wear colored contact lenses for Halloween?

The FDA says not to wear decorative colored lenses unless an eye care professional has fitted you and given you instructions. If eye effects matter to the costume, makeup around the eyes is the safer route, after a patch test.

How far ahead should I test Halloween face paint?

The FDA suggests testing makeup at least 24 to 48 hours in advance on a small area, such as the arm, of the person who will wear it. If redness, swelling or a rash appears, don't use it on the face.
