I'm just wondering this. It probably won't change anything I do, but I was curious of the responses.
So, my mom is a big support of matching bra and panties. I, however, am into neutral bras (nude, black, and white. I do have some fun ones for when I got to Rocky Horror and a Cheetah-print one I've become rather fond of) and crazy/cute panties. I have the sexy, lacy ones, and cute patterned ones. I rarely match them unless my outfit requires it (needing to wear white or black is usually the case). But do guys care?
Again, I'm not gonan throw out my fun panties if you guys say you prefer matching, but I though it'd be interesting to see.
