The document discusses costume design choices that characterize and symbolize the protagonists in a story. The main character's simple leggings and ballet shoes represent her dream of being a successful dancer, though the leggings will rip, signifying the end of that dream. Her boyfriend will wear a tracksuit and hoodie to appear intimidating and portray the stereotype of an abusive partner, leading to the protagonist's suicide. His dirty shoes, messy tracksuit, and sloppy appearance aim to depict him as a careless and horrible person, generating empathy for the main character.
