This morning, we asked readers of the Blackpool Gazette to share their little one's fabulous costumes and they did not disappoint.
In fact we received so many great pictures - over 300 - that we have had to make multiple photo galleries to show them all off.
You can see part one of the World Book Day gallery here but look below at even more of the amazing costumes from across Blackpool and the Fylde Coast...
