Skirt hands down unless we're going into a situation where a skirt might be too awkward like a football game where our seats are up high and a bunch of guys are gonna see up her skirt as we climb the stairs. If she doesn't care, I sure don't. I get turned on seeing other guys coveting my woman because I know I get to take her to bed and do all those things they can only fantasize about.
i feel the skirt makes an impression of easy going and fun loving. Also a small chance of possible seeing you naked in four to six dates later on. Pants say i'm less forward of any notion of sex, although it shows off the booty much better. Hmm, you know wear both! throw the fucker off haha.
