15 Cheap Halloween Costume Ideas for 2026 You Can Make at Home

Halloween is the perfect excuse to become someone — or something — completely different for one night.

But creating a memorable costume does not mean spending a fortune on something you may wear only once.

Some of the best cheap Halloween costume ideas can be created from clothes already sitting in your wardrobe, recycled cardboard and a few inexpensive craft supplies.

Better still, homemade costumes can be customised for adults, children, couples and families.

Whether you are preparing weeks ahead or desperately searching for something to wear on 31 October, here are 15 DIY Halloween costumes to inspire you in 2026.

1. Classic Sheet Ghost

Sometimes the simplest Halloween idea is still one of the most recognisable.

An old white sheet can become a classic ghost costume.

What You Need

An old white sheet
A washable marker or suitable fabric-safe material
Scissors
Dark clothing underneath

How to Make It

Drape the sheet carefully to work out where the eyes need to be.

Remove it before marking or cutting anything.

Create appropriately positioned eye openings with adult assistance where needed.

You can leave the ghost completely white or add a simple expression.

For a fun variation, add a hat, sunglasses or bow tie.

Safety tip: Make sure the sheet is short enough that the wearer cannot trip over it and that vision and breathing are completely unobstructed.

This is one of the easiest last minute Halloween costumes when time is running out.

2. DIY Black Cat

A black-cat costume is simple, comfortable and easy to recognise.

Start with black trousers or leggings and a black top.

Create two triangular ears from black card or felt and attach them securely to a headband.

Add simple whiskers using appropriate face paint.

A lightweight tail can be made from fabric or felt.

The advantage is that most of the outfit can come from ordinary clothing.

After Halloween, everything except the small accessories can return to your wardrobe.

3. Classic Witch

You do not need an elaborate costume to create a convincing witch.

Wear:

A black dress or black trousers.

A dark top.

Boots.

A homemade pointed hat.

A simple cape or shawl.

You can make a witch's hat using black card if you do not already own one.

Carry a lightweight decorative broom if appropriate.

For a modern version, replace the traditional black outfit with purple, green or dark red clothing.

A homemade witch is one of the most flexible cheap Halloween costume ideas because it can be spooky, funny or elegant.

4. Scarecrow

A scarecrow costume is particularly suitable for autumn because many of the pieces are normal everyday clothing.

You Need

Jeans.

A checked shirt.

A straw-style hat or old hat.

Fabric patches.

Appropriate face paint.

Attach removable fabric patches to the shirt and trousers.

Use makeup to create simple stitched details around the mouth and cheeks.

You can add small pieces of raffia to the outfit, but keep loose material away from the face and ensure it does not create a fire or trip hazard.

The finished look works for adults and children.

5. Mummy Costume

A mummy is another Halloween classic.

Instead of wrapping yourself in toilet paper, which tears easily and creates waste, use old white fabric strips.

Wear light-coloured clothing underneath.

Loosely attach fabric strips around the clothing.

Do not tightly wrap the body.

Keep the neck, face, hands and feet unobstructed.

Add a little washable grey or brown colouring to some strips if you want an ancient appearance.

The costume looks more convincing when the fabric is slightly uneven.

6. DIY Skeleton

You can create a skeleton using black clothing and white material.

Start with:

A black T-shirt.

Black trousers or leggings.

White felt, fabric or removable tape.

Create simple bone shapes and attach them to the clothing.

You do not need anatomical perfection.

The basic ribcage, arms and leg bones are enough to make the idea recognisable.

Finish with suitable black-and-white face paint if desired.

For children's costumes, prioritise comfort and visibility over detailed makeup.

7. Mad Scientist

This is one of the easiest costumes to create using second-hand or household items.

Try:

A white coat or oversized white shirt.

Dark trousers.

Safety-style glasses used only as a costume accessory where appropriate.

Messy hair.

Rubber gloves.

A clipboard.

Add handwritten labels such as:

TOP SECRET EXPERIMENT

LAB 13

DO NOT TOUCH

You can carry an empty, clearly decorative plastic container as a pretend experiment.

Never use real chemicals, laboratory substances or dangerous materials as costume props.

8. Tourist

Need a costume in ten minutes?

Become an enthusiastic tourist.

Wear:

A colourful shirt.

Shorts or comfortable trousers.

A sun hat.

Sunglasses.

A backpack.

A camera.

A printed or hand-drawn map.

Add a homemade badge saying:

FIRST DAY HERE!

This costume is inexpensive because you may already own everything.

It also avoids heavy makeup, masks and uncomfortable accessories.

9. Bank Robber Duo

This can be a fun costume for couples or friends.

Wear black trousers and striped or dark tops.

Create simple eye-mask shapes from suitable lightweight material, making sure vision remains unrestricted.

Carry an obviously fake fabric money bag labelled:

$

or

£

Do not use realistic weapons or props that could be mistaken for genuine criminal equipment.

The costume should clearly look playful and theatrical.

A friend can dress as a fictional detective or security guard to create a group costume.

10. Retro Fitness Instructor

Look through your wardrobe or a second-hand shop for colourful sportswear.

Think:

Bright leggings.

A colourful T-shirt.

Shorts over leggings.

Headband.

Wristbands.

Trainers.

Add a homemade sign or badge saying:

FITNESS CLASS — 1986

The more mismatched the colours, the better.

This is a comfortable option for parties where you will be walking or dancing.

11. DIY Zombie

Old clothing can become a zombie costume instead of being thrown away.

Choose clothes you no longer need.

Create a worn appearance using safe, washable or permanent craft methods appropriate to the clothing.

Add grey, brown and dark-red tones carefully.

Use suitable costume makeup to create a tired, spooky appearance.

You do not need graphic gore.

Dark circles around the eyes, messy hair and distressed clothing are enough to communicate the idea.

This makes the costume more suitable for family events as well.

12. Cardboard Robot

Delivery boxes can become an entire Halloween costume.

Choose a cardboard box large enough to fit comfortably around the torso.

Create appropriate openings for the head and arms.

Decorate it using:

Silver paper.

Paint.

Bottle-cap-style decorations.

Drawn buttons.

Paper dials.

Colourful shapes.

Add a smaller lightweight headpiece if it can be worn safely without restricting vision or ventilation.

Write something funny on the front, such as:

ROBOT 2026

BATTERY LOW

or

NEEDS COFFEE

Cardboard costumes should be kept well away from flames, candles and other heat sources.

13. Rain Cloud

Want something unusual?

Turn yourself into the weather.

Wear grey, blue or white clothing.

Create a lightweight cloud from suitable craft materials and attach it to a secure headband or hat.

Hang lightweight blue paper raindrops from the cloud.

Alternatively, attach cloud shapes to a shirt instead of wearing a headpiece.

Add a small sign:

100% CHANCE OF HALLOWEEN

This is an easy costume that works without expensive accessories.

14. Family Emoji Costumes

Family costumes do not have to be complicated.

Choose several familiar facial expressions.

Cut large circles from yellow card or suitable lightweight craft material.

Draw a different generic emoji-style expression on each one.

Attach the circles securely to clothing without restricting movement.

Possible expressions include:

Happy.

Surprised.

Laughing.

Sleepy.

Silly.

Children can choose their own expressions and help with decorating.

If you plan to post or sell designs rather than simply make a personal costume, avoid copying proprietary branded artwork exactly; use your own generic facial-expression designs.

15. Haunted Portrait

Our final DIY Halloween costume is perfect for people who want something unusual.

Dress in old-fashioned or formal clothing already available at home.

Create a lightweight cardboard picture frame.

Decorate it with gold, black or brown paint.

Hold the frame around yourself so that you appear to be a portrait that has stepped out of a haunted house.

Use pale costume makeup if desired.

Stand still when someone approaches, then suddenly change expression.

It is part costume and part performance.

Just make sure the frame is lightweight, has smooth edges and does not obstruct movement.

How to Make a Halloween Costume Look Better Without Spending More

A cheap costume does not need to look unfinished.

The secret is consistency.

Choose one clear idea.

Then make every part of the outfit support it.

For example, if you are dressing as a mad scientist, you do not need ten expensive accessories.

A white shirt, messy hair, glasses and a clipboard may communicate the character immediately.

Adding more items does not automatically make a costume better.

Shop Your Wardrobe First

Before buying anything for Halloween costumes 2026, look through what you already own.

Search for:

Black clothing.

White shirts.

Old jeans.

Checked shirts.

Scarves.

Hats.

Boots.

Sportswear.

Formal clothing.

Old sheets.

Accessories.

You may already own 70% of a costume.

Build your idea around those items rather than choosing a costume first and then buying everything from scratch.

Visit Charity Shops and Thrift Stores

Second-hand shops can be excellent places to find inexpensive costume pieces.

UK readers can check local charity shops.

US readers can explore thrift stores.

Look for items that can be reused after Halloween.

An ordinary black jacket is more practical than an expensive single-use costume if both can achieve the same effect.

Second-hand shopping can also make a costume more unique.

Use Cardboard Before Buying Plastic Props

Cardboard can become:

Robot armour.

Picture frames.

Signs.

Masks.

Shields.

Tombstones.

Costume badges.

Fake control panels.

It is inexpensive, lightweight and often already available from deliveries.

Paint and imagination can make cardboard surprisingly effective.

However, keep it away from flames and ensure costumes remain easy to move in.

Best Last-Minute Halloween Costumes

If Halloween arrives and you still have no costume, do not panic.

Some of the quickest options from this list are:

Black Cat — black clothing + homemade ears.

Tourist — colourful clothes + camera + map.

Ghost — appropriately prepared white sheet.

Mad Scientist — oversized white shirt + messy hair.

Retro Fitness Instructor — colourful sportswear + headband.

These can potentially be assembled from things already in your home.

Cheap Halloween Costumes for Adults

Adults often want costumes that are inexpensive but still comfortable enough for an entire evening.

Good options include:

Tourist.

Witch.

Retro fitness instructor.

Scarecrow.

Mad scientist.

Zombie.

Haunted portrait.

Choose lightweight costumes if you will be travelling between venues.

Comfort becomes particularly important when a party lasts several hours.

Cheap Halloween Costumes for Kids

Children's costumes need extra attention to safety.

Simple ideas include:

Black cat.

Scarecrow.

Robot.

Skeleton.

Ghost.

Rain cloud.

Emoji.

Make sure children can:

See clearly.

Walk comfortably.

Use stairs safely.

Move their arms freely.

Breathe normally.

Avoid costumes that drag along the floor.

If children will be trick-or-treating after dark, visibility is also important.

Consider reflective elements or lights where appropriate.

Halloween Costume Safety Tips

A creative costume should also be safe.

Avoid long trailing fabric that could cause falls.

Keep flammable costumes away from candles and open flames.

Make sure masks and headpieces do not restrict vision.

Use skin-safe products intended for cosmetic use when applying face paint.

Test products appropriately if allergies or sensitivities are a concern.

Choose footwear suitable for walking.

Children should have appropriate adult supervision.

Battery-powered LED lights are generally safer around costumes than real candles.

Don't Use Realistic Weapons

A Halloween costume does not require a realistic weapon.

Props that resemble genuine firearms or other weapons can cause fear, misunderstandings and serious problems in public places.

For costumes such as a fictional robber, detective or action character, choose obviously playful alternatives or simply skip the weapon completely.

A costume should look like entertainment, not a genuine threat.

How to Save Your Costume for Next Year

Do not throw everything away on 1 November.

Separate reusable pieces.

Store:

Hats.

Headbands.

Fabric.

Capes.

Decorative glasses.

LED accessories.

Craft materials.

Neutral clothing.

A witch hat might become part of next year's costume.

Black clothing can become a cat, vampire, witch, skeleton or dozens of other characters.

A small box of reusable Halloween accessories can save money every year.

Create a Halloween Costume Box

Families can go one step further.

Keep one storage box containing reusable costume items.

Add:

Old scarves.

Hats.

Safe costume jewellery.

Capes.

Fabric pieces.

Headbands.

Gloves.

Face-paint supplies within their usable dates.

Craft materials.

Children can combine them differently each year.

Instead of buying a complete new costume every Halloween, you gradually build a collection.

DIY vs Store-Bought Halloween Costumes

Store-bought costumes are convenient.

DIY costumes offer different advantages.

They can be:

Cheaper.

More original.

Easier to customise.

More comfortable.

Reusable.

A mixture of both approaches can also work.

You might buy one inexpensive accessory and combine it with clothes you already own.

There is no rule saying a Halloween costume must come from one package.

Halloween Costumes in the USA and UK

Halloween traditions differ slightly between the United States and United Kingdom, but costumes are popular in both.

US families may need costumes for school events, neighbourhood trick-or-treating and large Halloween parties.

UK families may attend parties, community events or go trick-or-treating locally.

The cheap Halloween costume ideas in this guide can be adapted easily for either country.

Use dollars on a pretend robber bag in the USA or pounds in the UK.

Use thrift stores in America or charity shops in Britain.

The basic DIY principles remain the same.

Transform an old white shirt into a mad-scientist coat.
