No dress code

I saw a guy at the coffee shop this morning who probably can't get into an arena bar in Columbus. He was wearing a sleeveless vest (it was about 15 degrees with a high wind) with no shirt; cowboy boots; wrist bands on both arms; bandana tied around his upper arm; a silver container(?) poking out of his back pocket (skin tight jeans); dangling key chain; some jewelry. As I left I saw him copying down phone numbers from his cell phone to a piece of paper.
