untucked , partially unbuttoned, "casual" button down, longsleeved shirt look? I know that this is the "official cool yet casual look" for guys aged 16-50 or something, but I think it i just looks assine. I am an all or nothing at all type of guy. If you are going to go casual, just wear a t-shirt or sweatshirt or polo with jeans. If you are going to wear a button down, longsleeved shirt, just wear dress slacks and tuck the damn thing in. I am assuming that I am alone in this opinion, since every guy I see seems to dress like this whenever he is heading out on a date, to the club/bar, party, etc.
