FG, you have to understand that different folks have different preferences--both providers and hobbyists.
Let's say that ten percent of my clients prefer lingerie, ten percent prefer jeans, twenty just want something flattering, and the other sixty just want me out of all the clothes as quickly as possible... really, I should probably be answering the door naked and be quit of the whole charade, right?
Wrong. Because most of the time, the persons who find the particular outfit very important will *mention* it. And if you can't rely on them to mention it, guessing wrong is just as likely to offend as going with your own preference. (Even the most likely scenario in this instance is only slightly more likely than the other options.)
So I wear cocktail dresses and a garter belt, because it makes me feel sexy. As a result, I've put the most work into developing this part of my wardrobe, and know that my dresses will flatter my figure and coloration. Which makes me feel even sexier.
If you want lingerie? Great! I'll wear lingerie. But only if you *tell me*.
Assuming that providers are reading your mind, and then getting irritable when they don't, isn't going to make anyone happy.
Oh, yeah, it occurs to me! If you're still anxious about mentioning preferences, this site has an absolute wealth of information from folks who've seen all stripes of girls in all sorts of locations. Why not check for the one whose clients report she's always wearing lingerie?
It's all in your hands.
