Surprisingly good product.
Size: 5X-Large, Color: Grey Black
Came exactly as suspected. When ordering a 3 piece tux I expected to find some sort of problem or something that didn't fit, but I was pleasantly surprised. Looks like the photos and fits as advertised. So very happy. Doesn't look cheap or gimmicky. Thank you!

Good quality stank fishy smell
Size: Small, Color: Silver
Beautiful but it stank badly smells like fish. Wherever y'all have it stored in when y'all have it needs to be cleaned out. Now I have to take it to get cleaned/steamed because of this stank smell. Need give me some of my money back much as it cost. Now I got to pay get smell out of it is ridiculous. Cost to much for this to smell how it smells.
