Fairly good quality. Hubby wore this as fun alternative to his regular tux in a cruise elegant night. Looked sharp and we even got family pictures in it.

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.

Ready for the “Wild Elegamce “ ball!
Color: Red, Size: X-Large, Color: Red, Size: X-Large
It runs a little small so even though I usually wear a large, the extra large is good for me as recommended by other buyers. It’s going to be perfect for iur “Wild Elegamce” fundraiser ball in October!
