Looovveeee it!!
Size: Medium, Color: Royal Blue, Size: Medium, Color: Royal Blue
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

Misleading
Size: Small, Color: Brown
This is a very horrible material and poorly made suit, I have never bought anything this bad in amazon before, the crazy thing is that I returned this thing to get a refund and they shipped back the exact same garbage back to me.
I clearly do not like anything about it, this is a misleading advert
