I care more about the panties than I do the bra. Which is interesting because I'm a full-fledged card-carrying member of the breast man club. Tight tank tops with no bra is especially hot.
As for panties, I like pretty much anything without too many bows and without too much frilly stuff. It shouldn't look too complicated...when I remove them I don't wanna lose a finger in the process.
Something that's semi see through is a huge turn on for me because I love seeing a little bit of pubic hair shining through. And for some reason the colors turquoise and red have always resonated with me. Black is also really nice if the top matches.
As for styles, I'm pretty easy to please as long as they don't look like briefs. Boy shorts are hot, cheekinis are hot, hip hungers are hot...they're pretty much all hot.
I like teddies, garter belts, thongs, hot pants, body suits, thigh highs, and whatever makes my woman feel sexy. While men are more visual, the sexier she feels, the naughtier and more confident she gets, and that's what matters most.
