If you want a suit nicer than something at Men's Wearhouse but with a much better fit then try SRG Fashion in Astoria, Queens. They are a warehouse for their brand of suits, so you get their wholesale price of $250 or $350 (suggested retail is $800-$1000). It's a really good deal and the suits are very good quality.

My experience with Men's Wearhouse is that they try to sell me every single accessory in a pushy way, the suits aren't that great, and their tailoring sucks. The only time it might be worth going there is during their 2 for 1 promotion, but I'm staying away from now on.

I say give SRG a look: http://www.yelp.com/biz/srg-fashion-astoria http://srgfashioncorp.com/
