Not even close on the size
Size: 3X-Large, Color: White
Size is not even close to correct. Ordered a 3xl but the actual size was closer to a XL or even a large. Be wary on the sizes. They are not accurate

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.
