I wear black non-cotton 3 button collared shirts almost exclusively when not at home. I will also wear tanks, usually a basketball jersey style when weather dictates. I have about 3 t-shits that actually look decent. I have gotten more comments on my physique, and it's nothing special by our standards here, in the black golf shirts than anything else.
Almost forgot: ANYTHING 100% cotton will be worn once if free and then in the bin. I refuse to buy 100 cotton as they NEVER fit correctly after being laundered, and yes washed cold and no heat used to dry............pre-shrunk my ass.
