The Cat in the Hat

Last but not least is Thing 1 and Thing 2 from the Dr Seuss classic The Cat in the Hat! This World Book Day costume for brothers and sisters couldn’t be easier – just choose between the jumpsuit and dress versions, both of which come with Thing 1 and Thing 2 patches. If you have a third child who wants to go as The Cat himself, we have an easy jumpsuit costume or you could try to make your own at home!

We’re sure one of the kids will be desperate to be Peter himself, but the others can choose between Hook, Tinkerbell and the crocodile – depending on whether they want to help or hinder!
