Bought this for my son. This is the second suit from this company that I've purchased and the quality is great. The material isn't cheap. My boy looked very nice and he received a lot of compliments.

Prom Suit
Color: Blue, Size: Medium
It came fast but the pants was still kind of big on my son he’s in a small for everything and I fix the jacket because the arms was a little bit long but my son loved it and said it was comfortable. Maybe size down if you can.
