World Book Day Costumes for Adults: Creative Ideas for Teachers, Schools and Libraries

World Book Day is one of the most anticipated events in the UK school calendar. For teachers, teaching assistants, librarians and nursery practitioners, it is the perfect opportunity to bring books to life and inspire a love of reading through imaginative costumes and themed activities. Choosing the right World Book Day costume for adults can transform a simple classroom lesson into a memorable experience that children will talk about long after the day is over.

At Costumalia, you'll find a wide range of World Book Day costumes for teachers and adults, from iconic literary characters to creative group themes designed for entire year groups, departments or schools.

World Book Day Costumes for Teachers

Teachers often look for costumes that are instantly recognisable, classroom-friendly and linked to books children actively read in UK schools. While traditional fairytale characters remain popular, many schools now favour modern children's literature and contemporary classics.

Some of the most popular World Book Day teacher costume ideas include:

Matilda and Miss Trunchbull

One of the most successful costume pairings for primary schools. A teacher dressed as Miss Trunchbull alongside another colleague as Matilda creates an instantly recognisable theme that children love.

Gangsta Granny

David Walliams remains hugely popular in UK schools. Dressing as Gangsta Granny is both easy and effective, especially for Key Stage 1 and Key Stage 2 events.

Mr Twit and Mrs Twit

Roald Dahl characters continue to dominate World Book Day celebrations. The Twits offer plenty of opportunities for humorous costumes and classroom activities.

The BFG

A giant pair of ears, waistcoat and friendly giant appearance make the BFG one of the most popular teacher costumes year after year.

Billionaire Boy

Another David Walliams favourite that resonates strongly with modern pupils.

Group Costume Ideas for School Staff

Coordinated costumes often have the biggest impact during school assemblies and reading events. Staff groups dressing around a single book create an immersive experience that encourages discussion and engagement.

Alice's Adventures in Wonderland

One teacher can be Alice, while colleagues become the Mad Hatter, Queen of Hearts, White Rabbit, Cheshire Cat and Tweedledum and Tweedledee.

This theme works particularly well for larger schools and library events.

Charlie and the Chocolate Factory

A complete staff-room favourite in the UK.

Ideas include:

  • Willy Wonka
  • Oompa Loompas
  • Violet Beauregarde
  • Augustus Gloop
  • Veruca Salt
  • Mike Teavee

The colourful costumes make this one of the most visually striking World Book Day themes.

Harry Potter Staff Theme

Teachers can become Hogwarts professors, while support staff dress as students, Hagrid, Dobby or magical creatures.

This remains one of the most searched-for World Book Day costume themes in Britain.

The Lion, the Witch and the Wardrobe

Perfect for English departments and older primary classes.

Characters can include:

  • The White Witch
  • Aslan
  • Lucy
  • Mr Tumnus
  • Edmund
  • Peter
  • Susan

Original World Book Day Costume Ideas for Adults

If you're looking for something different from the usual literary characters, there are plenty of creative alternatives that stand out.

Where's Wally?

One of the easiest and most effective costumes for teachers. It also creates interactive games where children try to spot "Wally" throughout the school day.

The Day the Crayons Quit

Each teacher dresses as a different coloured crayon. This works brilliantly for Early Years and Key Stage 1 settings.

A huge favourite in nurseries and infant schools across the UK. Staff can coordinate using different colours representing different emotions.
