I underdress all the time. I don't own any male clothing at all, except for a large collection of 17th century type shirts and jackets. I guess you could say I'm more of a cross-over dresser, blending the feminine look with a male style long since forgotten. I have about 40 pairs of panties (cotton, lace, etc), and I wear pantyhose whenever I can. Over that I wear jeggings / jodpur type pants, female leather boots, big white shirt and 17th century style jackets. It's not really underdressing as such, because all my friends know what I wear underneath anyway. I sometimes wear a short shirt instead of the jeggings; a kind of 17th cnetury Goth Scottish look, but it's often too cold for that. I very lucky; my GG and all my friends think I rock the look. Hoping to start a new fashion trend.
