World Book Day is just around the corner so it's time to start thinking about World Book Day costume ideas to inspire and encourage your kids to read for pleasure.

From Roald Dahl costumes to The Wizard of Oz fancy dress to Harry Potter we've got a collection of the best World Book Day fancy dress for kids and teens.

Alice In Wonderland Costumes

Lewis Carroll’s crazy world of Wonderland has introduced children to a whole host of unforgettable characters, and you’ll find Alice in Wonderland World Book Day costumes for all the best ones here! We’ve even got some step-by-step make-up video tutorials for you to try, too.

  • 1. The Mad Hatter

    The books are full of brilliant characters, but for many, the Mad Hatter will always be the best. In recent years, that’s probably partly down to Johnny Depp. However, we think the Hatter has always had one of the coolest costumes around, and World Book Day is a great time to give it a try!

    You can even do your child’s make-up for them with this Mad Hatter make-up tutorial!

The Wizard of Oz Costumes

When it comes to The Wizard of Oz, you could argue that the film is more famous than the book. Indeed, L. Frank Baum’s novel is well over a century old. However, Dorothy and her travel companions remain as iconic as ever, so discover our Wizard of Oz fancy dress for World Book Day.

    We all know how much Dorothy loves being at home, but we’re sure she won’t mind spending a day at school!

    And what about Toto? Your child’s school is unlikely to be happy with a dog running around the classroom, but this fun Dorothy fancy dress accessory comes complete with a cuddly pooch, so he won’t miss out on the fun!
