DenimBar is a great shop with a great discount (like Tsukasa said), but they sell out quickly.
styleforum.net has coupons for Context Clothing (15% i think)
revolve has them and you get 30% off for you first ever order if you call them.
you're in NYC, so there's a bunch of B&M places - GO TRY THEM ON FIRST. THEY STRETCH LIKE IT'S GOING OUT OF STYLE! SIZE DOWN 2-3!
oh yeah, and it's styleforum-dot-net, not dot-com.
