It's book week at school, and non-binary Riley and their best friends craft hard for Dress Like Your Favourite Character Fancy Dress Friday. Colourful fabric! Paint! Glitter! They are ready to make the biggest and best group costume ever! But most of the other kids are having trouble coming up with costumes. Riley is ready to use their creativity and vision to help as many kids as possible so that dress-up day will be a big success!
