In most of your photographs you're wearing stockings and look beautiful.  You have a lean, classy sophisticated. I would guess that most men want to meet the beautiful woman in the pic's

I can only speak for myself. I like it when a girl wears those types of outfits because I want her to give me an impression that she is a dirty filthy provider. There is nothing like being with a girl that is dirty, filthy, and is willing to do anything I want. There shouldn't be any barriers to achieve great sex. Often times, being with a civie girl, there are limitations and barriers for sex. Some civie girls don't want to explore or don't want to act in a way that makes them a filthy and nasty. That's where the fantasy aspects comes into the hobby.  

Those types of outfits usually tell me a lot about a girl. Not always, just sometimes. Not only is it visually appealing but it also stimulates the session because the mood is set. That mood is she is presenting herself to be my filthy and dirty girl. The most nastiest sessions are the most memorable sessions. Also, as it relates to the fishnet outfit, most guys want to experience a fantasy of being with a pornstar. When I see a girl wearing a fishnet outfit on a porn video, then I can expect that she is about to get real nasty, and I like me a girl that gets real nasty.

I like the fishnet outfit as a presentation, but when I'm fucking, I want it off. You asked and I'm giving you an honest answer, at least from my perspective.

...to me. I love to see a woman dressed in sexy stockings, especially if she's wearing a nice, not too revealing dress. (Read as not skin tight, showing cleavage and leaving little to the imagination.)

Removing the dress and getting a look at the full picture of stockings, heels and lingerie builds the anticipation. Not to mention sliding off the heels and slowly removing the stockings to reveal gorgeous bare skin below

I think it's the look... HOT!!!

and it's a little bit slutty which is always nice.

I also like smooth, bare legs.

I do NOT like fishnets.  They seem too trash for my taste.

So, IMHO if it costs a bit then you should buy it in her size or bring that as a tip... But I'm curious.. What IS IT??

I love seeing a woman in sexy fishnets, thigh-highs or boots. To me, these sexy items (as well as any slutty outfits) help really accentuate my experience because these are not things that a civilian woman would normally wear.

Thigh highs, no panties, cow girl...is awesome.  Why, I don't know.  Kind of like how half dressed is always sexier than full nude.
