I find thigh highs extremely erotic on women. I think they might be making a comeback, but that might be more about where I live and work than anything.
But let me riddle you this...Is it the look you're after, or the feel?
Visually speaking, thigh highs are among the cheapest ways to add an alluring thrill or flair to an outfit...but when it comes to doing the deed, I find that most thigh highs are rough round the garter. Additionally, most are made out of nylon, a high-friction material sewn in a canvass stitch. Under friction, this is probably one of the more sandpaper like surfaces one could find outside the hardware store.
So I think if you really want to go all out, silk is in order.
