World Book Day Costumes for Children

For children, choosing a World Book Day costume is often half the fun. One minute they are getting ready for school, the next they are Harry Potter, Matilda, Paddington Bear or The Gruffalo heading off on an adventure.

Some characters never really go out of fashion. Harry Potter, Willy Wonka, Peter Rabbit, The Cat in the Hat and Paddington Bear are always popular because children recognise them straight away, and so do parents, teachers and grandparents. That makes them a safe choice when you want a costume that feels fun, familiar and easy to connect with a book.

Many schools also encourage children to choose a character from something they are reading in class. It is a lovely way to make stories feel less like homework and more like something they can actually step into.
