They say you should dress for the job you want, not the job you have. That could be this man's strategy dressing as... well, I'm not exactly sure what to call that. In reality, this guy was trying to get some Hamilton tickets so he thought if he dressed up then someone would take pity on him and give him the lottery ticket. That's the tickets they give out to people every performance as a way to make up for the fact that tickets are $1,000.
I hope he wasn't wearing that during the Summer months. I can't imagine being in the New York heat wearing a one hundred piece suit. Sure, that's what people from that time period had to do, but screw that. That's why I live in the now. The time of air conditioning.
