nylon panties for sure, Shadowline Nylon is one of the best, Dixie Belle, Carole, and Bali Free Form. Satique.com is temporarily down. but they do have amazing quality fabrics. I had them make custom split crotch briefs for the wife and I years ago so we could **** with our panties on. I also like to wear mine with my parts through the split and then several regular panties on over that so my parts are sandwiched between the nylon! watch out, it's a lot of fun!
