Nice suit for a low cost
Size: X-Large, Color: Black
Perfect, true size! I don’t think you could get it a better suit for the price. Lots of compliments.

True as advertised
Size: X-Large, Color: Wine Red-2, Size: X-Large, Color: Wine Red-2
Great fit, true to size. I am 6'2" 217 lbs and bought the XL. The color is just as expected and the cut feels and looks tailored. This suit looks like aand feels expensive while being extremely budget friendly.

5’-11”, 185 lbs, Size- Large
5”-11”, 185 lbs, size Large. Suit jacket fits good and has some weight to it. My chest is a little bigger proportionally for my size but if I go with a size up, the jacket would be too big. Vest fits good but appears to be XL though it is labeled L. Not a big deal. Pants are also a good fit. Waistband is not too tight or too loose around my waist. Pant length is a little long but still a good fit. I normally wear 34x34 pants.
