The document outlines the proposed costumes for three characters - a detective who is also the serial killer, the detective's partner, and a victim - in the opening of a mystery/thriller film. The detective will wear stereotypical detective clothes like a long coat and fedora to clearly identify him as a detective. The serial killer will only need trainers shown to depict walking away from the crime scene. In contrast, the partner will have a more casual look through a bow tie, glasses, and jeans to hint that the main detective is actually the killer. The randomly dressed victim in casual clothes is meant to suggest the killer targets with no clear motive.
