I remember years ago, I saw a provider that had a separate incall apartment downtown that she didn't live in, and she had just gotten there as I was arriving. She was wearing sweats and pretty much no makeup. She apologized for running late and ran into the back room for a minute to change into something sexy. I don't remember what she came out in, it may have been lingerie, or a robe, or whatever... Whatever it was, it wasn't really memorable, which is pretty telling. Because to this day I still remember how she looked in the sweats.
Like most women, she just had no clue how pretty, how unbelievably sexy she looked just being the unprepared girl next door. I think lingerie makes an encounter feel prepared, planned, anticipated... Which is great. But average looking street clothes and not much make up and hair not quite perfect... For me, that FEELS like a whimsical, playful, lusty chance encounter that wasn't planned, even though it obvious was planned.
My very first meeting ever in the hobby was jeans, an oxford short, and these super heavy heather socks. And she looked like a million bucks.
I think it depends on the woman's appearance and personality too. What I would like Trinity to answer the door wearing may be very different than what I want to see Casey answer the door wearing. Casey, you have a frigging ton of girl-next-door going on, for you my perfect outfit would be casual, comfortable street clothes over amazingly average undergarments, removed a piece at a time as we mutually undress each other on the walk from the door to the bed, leaving a trail of clothes that tell the story.
One thing... I DO have this thing for sheer black thigh highs, for as long as I remember. Not garters, not heels, just the stockings... And removing plain street clothes that are hiding a pair of thigh highs, holy crap that'd be the motherlode.
It just depends.
