[VaSteve]

I always wear an undershirt under a dress shirt. I like the way it feels better...makes the dress shirt "lay" better as well. Also helps if you sweat, I suppose, or makes you sweat a little. I'm unsure which causes which. What I don't understand is the wife beater. If you sweat, I suspect it's more the pits sweating than the body and the wife beater has to arms, so what's the point? I'm pretty hairy, so even if I didn't wear it for comfort, sweat, etc. I would wear one since I don't want that showing through.

Printed t-shirts underneath only if you're on travel and did a lame job packing.
