Old uniform shirt grey from age with pit stains and it's like cheesecloth it's so old, quadruple knit polyester uniform pants that are shiny from wear, and are snapping in the breeze because they're ankle height, and trashed out shoes that last saw a buffing cloth in 1993 are all OK because they're "official". But a smart jacket that no one will ever see is a no go. That's the world these guys live in.
