Colette is a character in the Thea Stilton books, and a member of the Thea Sisters.
She hails from France and she is raised there. She has a fashion-designing cousin named Julie, who she is really close to. Growing up, she continues her studies in journalism at Mouseford Academy along with her four best friends; Nicky, Pamela, Violet, and Paulina.
Colette wears pink jacket with beads on it, a blue turtle neck, long pink pants and a blue belt. She has light brown fur, blonde hair and blue eyes. She is seen carrying a small blue and pink heart-shaped bag.
In Thea Stilton and the Spanish Dance Mission, Colette's hair is straighter rather than her usual wavy hair. Also her bangs are not higher as her usual one. This hairstyle is retained in later books.
