Overall, great quality in suit the size was pretty good although the only thing that I wish that it had belt loops instead of an elastic band, but for the value of the money, you cannot beat that at all it looks great. It fits good. The fabric is soft and comfortable. If I could, I would buy this again definitely worth to buy.
