Personally, I LOVE a well dressed/groomed guy. It's such a turn on, and my friends all agree. An average looking guy can be hot just in the way he dresses, and vice versa, a hot guy can be a big turn off if he doesn't dress well or has bad hygiene. Good shoes, nice jeans, and a casual button down shirt is gorgeous.

White T-shirt and jeans? I don't know, but my girlfriend seems to like it.
