Henry Clarke Thompson • 2026-05-12 • Reviewed by Oliver Bennett

World Book Day 2026 falls on Thursday, 5 March, and for many families the search for a costume begins only days before. Most schools actively encourage DIY outfits made from everyday household items, and a growing number of parents are choosing budget-friendly, no-sew solutions over expensive shop-bought alternatives.

The cost-of-living crisis has pushed more families toward upcycled costumes, a trend that looks set to continue in 2026. Social media platforms like TikTok and Pinterest heavily influence last-minute searches, as parents seek quick inspiration using items already at home.

The official World Book Day charity promotes dressing up as any character from a book, not just classic ones, encouraging creativity.

What are some World Book Day costume ideas for girls?

Several popular book characters require little more than a few household items and a spare ten minutes. These options work equally well as gender-neutral costumes with small adjustments.

Gangsta Granny

This sassy character, inspired by David Walliams’ book, can be created with granny glasses, a grey wig or scarf, a striped top and skirt or trousers, plus fake jewels or cookies made from foil and paper. The costume is quick and also works for adults or teachers, according to MadeForMums.

Little Red Riding Hood

A red dress, hoodie, or cape made from a red scarf forms the base. Add a headband with wolf ears made from cardboard and a basket made from a bag with a paper handle. The Fancy Dress notes this can be assembled in seconds and paired with a wolf in grey clothes with ears.

Paddington Bear

A blue duffle coat or hoodie, red wellies or a red hat, a cardboard box painted as a suitcase, and a paper luggage label are all that is needed. Gathered suggests this works as a duo with an auntie character.

Zog the Dragon

An orange top and trousers, fabric wings cut from old orange clothes, and a cardboard mask with a horn and star create this brave dragon from Julia Donaldson’s book. MadeForMums includes this as a standout option for young readers.

Quick character hack

For Rainbow Fish from Twinkl, cover a top with coloured paper scales using safety pins or staples, and add a rainbow ribbon tail. This crafty option works well for group costumes and can be completed in under 20 minutes.

What are some World Book Day costume ideas for boys?

Boys’ costumes can be built from everyday wardrobe staples with a few simple additions. The following ideas are among the most popular across parenting resources.

Superworm

Pink clothes, a pink cape or towel, and a headband with paper eyes transform a child into Superworm from Julia Donaldson’s story. MadeForMums suggests rolling a towel to form the worm body and using a garden outfit as the base.

Fantastic Mr Fox

A jacket, waistcoat, or colourful scarf paired with fox ears or a cardboard mask and a tail made from a scarf or wool creates this Roald Dahl favourite. Face-painted whiskers complete the look, and the costume can be teamed with a chicken friend for a duo.

The Cat in the Hat

Black leggings and T-shirt, white gloves, a red scarf, and a striped hat made from a cardboard tube are all required. Whiskers drawn with face paint finish the iconic look. MadeForMums recommends pairing with Thing 1 and Thing 2 for a group theme.

Where’s Wally

A red and white striped top, blue jeans, glasses, and a red and white bobble hat create an instantly recognisable costume using items many families already own. Gathered highlights this as one of the quickest options.

The Very Hungry Caterpillar

A green outfit, egg carton or pipe cleaner body segments, and googly eyes bring Eric Carle’s character to life. Food props are optional but add extra fun. Gathered includes this as a low-cost favourite.

What are easy World Book Day costume ideas for teachers?

Teachers often need costumes that are professional enough for the classroom yet simple to assemble. The following options are suitable for a full day of teaching.

Mr Men and Little Miss

A coloured paper outfit shaped around the body, plus painted face to match the character colour, works for any Mr Men or Little Miss character. Twinkl recommends this as a group activity where each teacher or student adopts a different colour.

101 Dalmatians

A white shirt or dress with black painted spots, plus ears and a bow, creates a simple dalmatian costume. This can be paired with a Cruella de Vil outfit for a duo. Twinkl notes it works well for family groups too.

Tigger

A black and orange outfit, ears, a bow, and a book cover prop are all needed. Twinkl suggests carrying a basket for added character detail.

Generic Witch

Black clothes, oversized glasses, a broom, and a cardboard hat create a Harry Potter-style witch. The Fancy Dress recommends adding a wand for extra impact. This costume works for both teachers and adults.

No-sew classroom tip

Use safety pins, fabric glue, or double-sided tape instead of sewing. For a Peppa Pig teacher costume, author Liz Pichon demonstrated on This Morning how to use a paper plate painted pink with cut-out eyes, snout, and ears attached to a pink jumper. No rushing to buy – use items already at home.

What are some World Book Day costume ideas for adults?

Adults joining in with World Book Day need costumes that are comfortable, quick to assemble, and appropriate for a work or school setting.

The BFG

A long coat or trench, giant ears made from cardboard, and a bottle labelled “dream fizz” create Roald Dahl’s Big Friendly Giant. Gathered notes this works especially well for tall adults and teachers.

Diary of a Wimpy Kid

A plain outfit with glasses and a cardboard and paper mache overlay creates a recognisable Greg Heffley look. Gathered features a blog tutorial for this costume.

Mr Bump

Jeans and a blue T-shirt covered in bandages made from toilet paper or crepe paper, secured with safety pins. Gathered suggests adding a cardboard sandwich board for extra effect.

Work-appropriate reminder

Some workplaces and schools have specific dress codes. Check with your school office or employer ahead of time. Avoid full face masks, large props that obstruct movement, or any items that could be seen as frightening for young children.
