Bought this for my son's junior prom and it looked so good on him. I had to get a few alterations done because it was a bit too big for him but all in all great quality for the price.

This is a terrific purchase.
Size: Large, Color: Navy Blue, Size: Large, Color: Navy Blue
Amazing for the price. It’s a wonderful suit fit just right for a 5’10”. 145 pound male. The quality is surprisingly wonderful for this suit and the color is accurate. As in the picture it is a slim fit and accentuates his figure. I would highly recommend this for a purchase. (be sure to use the measurements on their description before ordering). After a steam and a press we were ready to go. The packaging was very nicely done also.
