20 of the Best Girl’s World Book Day Costume Ideas - Fancydress.com

We’ve made it to yet another year, which can only mean one thing… it’s almost World Book Day! If your girl’s a huge bookworm and often struggles to put her favourite story down before bed, then carry on reading. She may already have a favourite book character that she inspires to be like, but if not and she’s still undecided, then our 20 World Book Day costume ideas for girls is sure to inspire her. Watch as she transforms into her favourite character this March!


Mary Poppins

The first costume on our list of girl’s World Book Day costume ideas is the nanny we all know and love dearly, Mary Poppins. This nanny has real class, elegance and some believe her to have magic powers, as she falls from the sky with her trusted umbrella. If your girl loves the original Mary Poppins film, or adores the more recent movie with Emily Blunt, then she too can become the young version of the nanny this World Book Day.

Cruella De Vil

Does your girl have a rebellious side? Whilst she might appear nice and cute on the outside, she may just let her dark side slip this World Book Day. Along with her up-to-no-good helpers, Horace and Jasper, she’ll be out searching for those dalmations this March. Whilst she may not be evil just like the real Cruella, she can be a milder and cuter version of the iconic Disney villain. But watch out – just because she’s young, it doesn’t mean she’s any nicer!

Your girl has no doubt seen the Descendant films by Disney. It’s a highly popular series of movies that’s loved by young girls, as they find out if Mal, Evie, Audrey and Uma follow in their evil mother’s footsteps, or turn to the good side away from all evil. If their friends are also huge fans of this epic creation by Disney, they can become the ultimate Descendant gang this World Book Day. Which character will your little one choose to be?

Wizard of Oz Dorothy

As soon as your little girl puts on her Dorothy outfit, she’ll transport into another world. Only with the click of her ruby slippers can she return back home.
