Cassie has long natural blonde hair, blue eyes, and has a curvy "hourglass" figure, and is of average height. The clothes she wears throughout the episodes are usually blue, which symbolizes the character's sadness and loneliness.

Why does Cassie in euphoria wear blue?

Each character has a main color and style that is associated with them. For instance, Cassie wears baby blue and pink signifying how she has a naive innocence about her, while Kat changed from simple denim to a red leather dominatrix as she tries to break away from being the quiet, shy pushover.

Why does Cassie start dressing like Maddie?

“She has seen a lot in her short amount of time, so she's jaded and is imagining herself in the next chapter of her life and is even fantasizing about what it's going to be like to be out of school and have more freedom,” Bivens says. Cassie dressing like Maddy is a joke in the show as well.
