Buy the suit. Be sure to measure!
Size: Large, Color: Red, Size: Large, Color: Red
Suit looks better than the photo in person. The suit is also made well. Great fabric and pattern!
My son is 6'1 and weighs around 135-140 pounds. I ordered a size large for him so the pants would be long enough. The pants were a little big but it was nothing a belt could not fix. The jacket and vest fit well too. The item also arrived on time.
***Suit runs small BUT if you take out time to do the measurements you will get the correct size.***

Fits like a glove, looks like a million!
Size: Small, Color: Purple
Bought this as a gift for him and very impressed. Looks like a million dollars, fit true to size, looks tailored not cheap. Fabric is quality, stitching is done well and the pants have a nice hidden elastic extender that helps if he goes up or down a few pounds. Very impressed!

It was the perfect suit for our big day!
Size: X-Small, Color: Purple, Size: X-Small, Color: Purple
Purple size xs. He's 5'9" 145-150lbs. Very impressed with this suit. The color and pattern is awesome. The fit was good. I would say this suit runs large. Usually he wears a Medium in everything but ordered an XS and it fit very well. The pants were long we had to get those hemmed. There was a few stray strings by the end of the night in areas of the suit. But overall good quality. And for a great price.
