There's a guy with a permanent booth at a local flea market, and it's absolutely covered in the most mallninjashit material you can possibly imagine, and the guy wears a trench coat, and a fedora.
When you talk to him, he's a totally normal dude who started doing this when he was a teenager and actually dressed like that unironically, but now it's basically his sales outfit. "playing the part" as it were. Outside the market you might not even recognize him
But boy does he love getting into character.
