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
