We were excited and I wanted to like it but...
Size: X-Small, Color: Black, Size: X-Small, Color: Black
We ordered this for Prom and it was supposed to be a size small, which was available for Prime ordering, but had to settle for xsmall. The pants, fortunately fit well and just need to be hemmed, the vest is great and the jacket is snug. My son has broad shoulders and I was hesitant to buy the xsmall, but it does fit just right. The only thing he would need to do is unbutton the jacket while he is dancing and maybe take it off while seated and eating dinner before prom. The material is surprisingly nice and has weight to it. I was relieved it isn't flimsy. The overall look on my son is smooth and we love the pattern and the material has shine to it. I was not happy that right out of the package, the button to the jacket could potentially fall off during because it doesn't look securely sewed in. The side of the right side of the jacket has thread already coming apart. And I found a little snag in a different location. I'm really not happy about that. I posted photos so you can see what I mean. We were excited about this suit, but it's going back. The company needs to do better with quality control.
