Great feel good suit
Size: Large, Color: Red With Goden
My husband looked so good in this. The color was popping. The size was true to fit and he’s very tall. Feels so soft and didn’t wrinkle at all. Very good material and fabric. Cheaper than I thought

Poor Quality
This suit was for my nephews school dance. The look is great however, its not of good quality. The material is cheap and looks as though it should be a costume. When my nephew tried it on it looked baggy. I returned the suit but have yet to receive a refund.

Awesome Suit!!
I purchased this suit for my boyfriend to wear to a party. I ordered an XL, he is 6'6" and 230lbs, initially the fit was fantastic and looks amazing but after wearing it and moving around in it for about 30 minutes, the pants started to slip down. The fabric has quite a bit of spandex in it and tends to stretch out after wearing for a little bit, it fits great right after it has been dried but then stretches out again. I ended up taking in the waist a little bit so the pants stay up, a large would likely have been a better fit. But he always looks amazing when he wears it and gets lots of compliments on the fun pattern. Definitely worth it!
