Boyshorts are by far the hottest underwear that a girl can wear. They can be regular styled, with nothing fancy, and they're still hot. Then, when you really want to get sexy, you can get the kind that are frilled and lacy around the edges, and that's even hotter. I don't think you can ever go wrong with those, especially in pink or black.
Well, some of us guys actually want it to coordinate. So, it depends on what outfit your wearing and the colors of the outfit, but matching to me is a must, so reply with some outfits and I would be glad to post my opinion.
