Isn't it kinda self explanatory? I'm sure Urban Outfitters or Hot topic has the pants. I've seen that necklace everywhere. And the pull over is in every legit men's clothing store.
I'd recommend the OP to just ask Adam Pascal for the costume but he'll probably still use it for the next 20 years or so. And on the 50th anniversary ReNt tour.

Just go to Williamsburg and ask any holier-than-thou, "too cool to talk to you" hipster you see on the street where he got his clothes. After he rolls his eyes at you and deems you appropriate enough to get off his i-Phone for a minute to answer, just go where he goes.

How do you know? You asked for help at 6:45, you get help at 6:50, and by 7:00 you are saving how hard it is to find the costume. In 15 minutes you couldn't have gotten your @$$ out of the computer chair and to the store and find out that they don't have anything.
