Personally, i find it sickening to see anyone's underwear unless it my own, or in the future my girlfriends.
I am rather disgusted by all the girls who wear low jeans so that when they sit down you can see their thong/g-string/asscrack. Hell, some of them even wear the øøøø which is bright orange. TO DRAW ATTENTION ON PURPOSE.
Personally i am more attracted to a girl who is not showing everything off. One that dresses neatly. There is just more respect you have to give them because of the way they dress. If a girl has some jeans, and a sweatshirt on, you can't see no skin, but i have a lot more respect for that girl than the girl wearing a lowcut belly showing, piece of cloth, with extreme amounts of cleavage showing, with a mini jean skirt which is so small it looks like a wide belt, which shows off everything.
Call me stupid, but that is what i believe, and or act upon. I'd rather go out with a girl who at least has a sense of self consciousness, than someone i percieve as a little ho.
