This is a men's dress shirt set. There are two button-down shirts, size LL, and two regular shirts, size L. One of the button-down shirts is described as short-sleeved, but the other three are unspecified. I purchased these in a hurry while on a business trip last year, but I didn't wear them, so I'm selling them. They are new and unused, but they were stored in a cardboard box, so please refrain from purchasing if you are concerned. No returns, no refunds, no exchanges (3N).
