A Desperate Search for a Suit in NYC

[Gugel]

I've spent almost a week shopping for a suit (in NYC) to no avail. Every suit I try on makes my frame looks "boxy". The jackets I try on might have the proper shoulder width, but the lapels tend to bludge out and the waist is way too big. Even tailoring will not get it to the correct dimensions without risking completely messing the suit up. Anyway, I went into H&M the other day and found one suit that fit my upper chest and another suit that fit my waist. I now know that I need a 41L Slim-Fit, but H&M didn't have any in stock and you can't order it online. I have been desperately searching for this size to no avail. I am willing to spend $500 on a suit that fits me well, but I can't find one. I've been to Macys, Men's Warehouse, H&M, and Banana Republic.

OOPers, I need your help! I need a suit! (I'm 20 years old and this is the first real suit I'm buying). Where should I go!? Thanks!
