I recently purchased suits for my "need to dress to impress" events. The consultants were there every step of the way. And, this includes helping me pick colors for the suits and the shirts, ties, socks, etc to match. (I am a guy, w/ no knows for color!)
The suits are nice, they have good selection in various price ranges, and if you can get there during a sale, you can often get suits at half-off or buy-one-get-one-free. FYI... **there is always a sale** - your average price per suit will always be the same - so just focus on the quality and price point you want.
I've also picked up a rental tux here for a friend's wedding and they didn't disappoint. Used the same measurements from my suits and made the fitting easy.
