I've always preferred retro to pantyhose. I also like to dress up so I prefer for a gent to let me know if they have a preference and if i can accomodate I'll let them know and if not, well I can always give them my sizes.
N I love corsets and girdles too, but don't have a good "girdle" just yet. One of my fav sites to "shop" at is secretsinlace they have sexy retro lingerie and hot models too hehe.
For me providing the proper attire to further enhance my companion's time with me is very important. It just takes asking and once again check the lady's site and note what she seems to prefer to wear there, you should be able to expect something similar in your meetings as well. (though perhaps not exactly the same, sometimes we borrow things for shoots hehe)
Now to go explore the pinup girl site again, I'd forgotten about that one!
