Costume explanation

A sports bag shows masculinity, in a dark colour it represents potential danger and adds suspicion to whoever the owner is.

Plain black jeans/trousers, they don’t give anything away as they're totally plain but they set an image of quite a laid back image.

A hoodie is renowned for setting a dodgy image, the edge is extenuated often by the hoodie being up, over their head and sometimes even over their face slightly.
