If you are looking for inspiration ahead of Thursday (March 3), then here are some of the best costumes from last year.
We took to Facebook to ask the people of Portsmouth to spread some joy by sharing photos of their little ones’ costumes for 2021.
Overwhelmed by entries, we chose 30 of our favourite pictures to share with you in this special World Book Day gallery.
From Superworm, to Norman the Slug, to a genius take on the Gingerbread Man, each image is bound to bring a smile.
Our trial offer starts at just £2 a month for the first two months.
