Add a black leather trenchcoat. Katana for flair, but not required

Columbine made black trench coats fall briefly out of fashion…but The Matrix brought it back a couple of years.
They were both 1999. Matrix released in March and Columbine was April 20th (made for a fucked up 4/20 that year…)
Yeah and immediately after there was some blame placed towards the Matrix.
