From Mad Hatters to Harry Potters and Willy Wonkas - they'll all be heading off to school today as Kent celebrates World Book Day.
Children and teachers across the county will be dressed as their favourite book characters for the national celebration.
World Book Day is held every year to celebrate the magic of stories and pictures, and to show just how much fun books and reading can be.
Here are some of your fantastic costumes.
And this year is special as it is the 20th anniversary of the event.
We want to see your costumes.
Above, we publish some of the first to be sent to us today - and they're fantastic!
Send us your pictures by emailing email@example.com, or tag us in on Twitter @Kent_Online
Since World Book Day began in 1997, more than 275 million book tokens have been given away.
