Although World Book Day is meant for book-lovers everywhere to celebrate the literary arts, one tradition remains at the forefront of the holiday: the costumes children don with their classmates at school.

One tiny feminist dressed as a suffragette, for a combined World Book Day and International Women's Day costume.

Here are some of the best from today:
