Excellent quality
Size: Large, Color: Purple
Perfect tuxedo to use for many functions. Got it about 2 years ago and have used it probably twice for galas as well as awards programs. Fits to size and didn’t break the bank. Texture is good and it is easy to pair with anything as well as is reusable.

The suit is amazing!! I just hate it arrived 3 days before prom after being delayed twice. It fit my son great, the blue was exactly as shown. It was not wrinkled or funny smelling at all. The material was very good and it will last a while. My son is 5’11, 150lbs, size medium
