It's undoubtedly one of the biggest days in the school calendar - and it's almost arrived for another year.
World Book Day will be celebrated on Thursday, March 1 - and we can't wait to see all of your costumes and pictures!
You came in your dozens last year to share pictures of your little ones in their finery, and we were treated to some truly terrific costumes.
And whether your favourite book character is a witch or wizard, superhero or animal, we can't wait to see your outfit on the day.
*Don't forget to share them with us on social media, or email them to us on the day at firstname.lastname@example.org - don't forget to include your child's name, age, where they're from and who they're dressed as!
