Magical Harry Potter Costume Ideas for World Book Day

Harry Potter World Book Day costumes

Can you believe it’s been over 20 years since we were first introduced to Harry Potter? J.K. Rowling’s wonderful wizarding world is as popular as ever, and that makes it a great source for your World Book Day costume ideas!

These Hogwarts heroes are instantly recognisable, and more than up to the task of dealing with the rough and tumble of the average Muggle school day.

So, we’re left with just one question. Which outfit will you choose? Let’s get you sorted!

Choose your Harry Potter costume

Well, we couldn’t really start anywhere else, could we? If your little one is set on heading to school dressed as Harry, we’ve got two options.

Hogwarts Harry

The first is this excellent officially licensed Harry Potter costume kit, which comes with everything your child needs for a day of Transfiguration, Potions and Defence Against the Dark Arts!

As you can see, all the little details are taken care of. You’ve got the classic Gryffindor robe with scarf and tie print, a wand and those unmistakeable round glasses. All you’ve got to do is draw on Harry’s lightning bolt scar before the school run!


Quidditch Harry

Is your child the sporty type? Quidditch is the only choice for the true Potter fan! They’ll recognise Harry’s smart red robes from the film series – just what they need before taking to the field. This costume is easily finished with just about any broom!

Hermione Granger

She’s the smartest girl at Hogwarts and she’s here to prove it!

Become our favourite Muggle-born witch Hermione (sorry, Myrtle) with this printed hooded robe, which comes with a magic wand and Gryffindor-colour hair bow.

Albus Dumbledore

So far, we’ve all assumed your child will want to dress as a Hogwarts student. But we’re all forgetting someone, and that someone is Albus Percival Wulfric Brian Dumbledore!

Yes, the much-loved Hogwarts headmaster is available as a World Book Day costume, and we’re sure you’ll agree his robes look pretty fancy! The long flowing robe even comes with his flat grey cap and a false beard.

Professor McGonagall

Another one of our favourite teachers, because who doesn’t want the power to turn into a cat?

This super cute Professor McGonagall outfit comes as a floor-length black dress with an emerald green cloak – just check out the detailing on the cloak’s edges, and of course it also comes with a black velvet witch’s hat!

Draco Malfoy

Ah, Malfoy. Sure, he let the Death Eaters into Hogwarts and nearly killed Dumbledore, but he can’t be all bad, can he? Okay, maybe he can, but this costume is anything but!

These black and green robes come decorated with the Slytherin crest and, after Snape’s sacrifice at the end of the books, we now know it’s okay to be sorted into this previously controversial house.

Newt Scamander

Newt Scamander fancy dress costume

The Potter universe lives on in the form of the Fantastic Beasts and Where to Find Them film series, and Newt Scamander is the star!

While we never met him in the original Harry Potter books, fans will recognise him as the author of the Hogwarts textbook that inspired this latest batch of films, so he definitely counts as far as World Book Day is concerned!

This outfit will be familiar to fans as the one worn by Eddie Redmayne in the films, so it’s just about the most current Potter costume you’ll find.
