Looks great. Size ok.
Overall looks great. The fit was good other than the pants were a little too long and the adjustable bow tie strap was a little to short. I'm 5'9.5" and 170lbs with longer than average limbs for a comparison.

Great feel good suit
Size: Large, Color: Red With Goden
My husband looked so good in this. The color was popping. The size was true to fit and he’s very tall. Feels so soft and didn’t wrinkle at all. Very good material and fabric. Cheaper than I thought

Poor Quality
This suit was for my nephews school dance. The look is great however, its not of good quality. The material is cheap and looks as though it should be a costume. When my nephew tried it on it looked baggy. I returned the suit but have yet to receive a refund.
