Stone-washed black — the chest has a pink employee badge: "Ask me about my Serpo — Serpo Abduction Services, ID: 00777." The back shows two round-faced figures in janitor uniforms against a green glow, with service terms listed in blue text above them. Completely committed to the bit. The people who recognise the reference will grab you by the arm — everyone else will just think it's a very confident uniform.
