I think the OP is serious.
gatorfan,
You may personally like the look, but most people on this forum will dissaprove. Let me add that I have only recently began to dress "like a man" as it were (I'm in my mid thirties). But even when all I wore were jeans, tshirts, long sleeve shirts, or short sleeve button down shirts I knew that showing your undershirt like the photos in this thread is REALLY TACKY.
The only thing tackier is when the sweater has a built in fake undershirt collar.
