Yeah, that ca and be pretty cute, depending on whether or not the guy is really pale, that would be kinda gross. But what I think is waaay hot (and all my friends think so too) is when a guy wears a button up collar long sleeve shirt, with jeans, but rolls the sleeves half way up, so hot!
I think guys look really great in that. It shows that they're comfortable to dress casual around girls. Like they're guyish enough to not try super hard. So leave the stressing about looking cute to the girls. A plain white tee is perfect
