Every guy like every woman is a little different

But as for me there is nothing sexier than a short tight dress.  
Something you probably wouldn't dare wear if we were meeting in the hotel bar...lol

I find certain outfits to be very stimulating such as yoga pants and crop tops, mini skirt gown/dress, a floral dress, or a sexy stripper outfit. Also, I'm a sucker for heels.

so i'm pretty specific, whatever role we're doing, the outfit matches.  but if my choices aren't available, i love short, tight, low cut dresses with high high heels.

Leg warmers and nothing else is the hottest IMO

I love to see women wearing boots. My favorite part of Winter. LOL

The short tight dress that shows cleavage and the hot body it's wrapped in. Heels too. Hard for that outfit to be inappropriate in Vegas.

Clients thanks giving feed back girls

with an opened short silk robe, pumps and a finger beckoning  
me to come hither. Also, totally dressed to the nines.

My usual answer is nekkid but that's for incall.

For outcall, it depends on the girl.

If she is the GND and her bod is just ok to good, a nice pair of jeans and conservative top works.

If she has long, great legs, a short cocktail dress and heels is preferred.

If she has that real cute, GFE, all American or sweet look, a sundress and flip flops can actually do it for me.

If it's a harder, more porn starish look, leather pants is a turn own.

Look at me. No wise ass answer and really answered an OP in depth for a change. I must be about to get laid.

Sports Jersey don't care what team. 2nd choice black tight dress.  

silky and lacy things.  I also like black wide fishnet.

If going out on the town, a gal should wear what compliments her body the best.  For some that is a backless gown, others it might be an elegant suit.  Each gal is very different in that manner

I like an oversized t-shirt or a towel wrapped around the chest.    Easy access for DATY

I prefer casual clothes. I am usually comfortable with how very beautiful the girls I have seen are, so no need to impress with fancy clothes.

I encourage new clients to purchase a set of Rasha Colorforms®. The vinly re-stickable playsets provide safe, creative and imaginative play to mix and match the perfect outfit from the comfort of your home. Just $19.99. And if you like dirty talk, why not add the new Rasha See N Say for just ten dollars more.

..It doesn't matter. It will be in a heap on the floor shortly and I am not turned on by undressing a woman. There is one outfit I like but escorts virtually never have it - greet me in a white terry cloth bathrobe with nothing on underneath. It did happen - once.

It depends on the mood and the particular session.

One day a professional outfit, e.g. white blouse, tight leather skirt, might fit the bill.  The next day maybe a catholic school girl outfit or a cheer outfit.

...it's the person inside them that matters...

...to be surprised when I arrive, so am not in the habit of making clothing requests.  I have on occasion suggested to a gal I wish to see again that less clothing is more.  Her meeting me naked under a simple robe that can quickly fall to the floor is a favorite.  Knee high socks on long slender legs gets me excited.  A short pleated skirt is another big turn-on.  The socks and skirt together and I turn to putty.

Whatever makes her feel sexy

Because if I find her attractive it almost doesn't matter. Plus it's all coming off pretty quickly anyways.

It shows off a bit, and is elegant. I always find it more sumptuous when a client gets to unwrap his present....it's also very sensual.

After years and years and years of going to rock concerts and seeing hot chicks in short, tight dresses, and not being able to do anything about it, I'm finally able to. I like slender women with great legs and nice boobs. There's nothing like seeing that kind of body in a short, tight dress with heels.

Two providers have looked so good that I asked them to walk across the room and back, just so I could watch every part move. The dresses don't stay on long, but they really get my blood flowing.

A new like for me is a tight fitting Mini dress, I also adore those sheer panel dresses

I enjoy role play, and most of my role play involves the woman being a slut, so the slutier, sexier the better.

I absolutely adore sluts, by far my favorite people.

Any of these:

If I am meeting her for:

The first time I prefer well fit jeans and the top of her choice. But only if she asks as I do not request any special attire on the first meeting.  

The second time I prefer Yoga pants and the top of her choice with nothing underneath either.

The third time I would prefer that she wear whatever she wants. Surprise Time.........

The fourth time or more I prefer absolutely nothing or a robe with nothing underneath.  

If at any time we are meeting first in public then I want her to wear whatever she wants.

I have never done the dress up role play meeting but am open to it without a doubt.

her website. The most interesting one so far has been a Dallas Cowboys cheerleader outfit. Unfortunately, that provider has retired.

Well, sort of.  In the summer, at least, I like it when my ATF wears a white shirt that I can pour some water on.  Other than that, I like fishnet stockings and other "bad girl" gear.
