Most of the time, I do wear matching bra/panty, to fit the atmosphere. But sometimes, I purposely wear non-matching bra/panty because I want to unmatch the top and bottom. For example, I plan on wearing a red top and a white skirt. In this case, I would wear a red panty with a black bra, just to maintain the contrast to “show off” my underwear. I guess I am just a slut.
