There is some debate about this, but one thing is hard to deny: clothing is sexy. Whether it's a silk nightgown from Victoria's Secret, a military uniform, the leather jacket of a biker or the riding clothes of an equestrienne, some form of clothing is usually someone else's ideal of "sexy clothing."
Fetish wear is usually clothing made of leather, latex, or rubber cut in a specific style to accentuate the body and show it off in a sexually arousing fashion. Fetish wear is a specific genre of clothing and as recognizable as such as swimwear or lingere. Fetish wear's most common characteristic is price; the stuff's expensive. Remember that it is only a fad, after all, and will be as out of style as the discowear of the 1970's. Eventually.
That depends entirely on who you and your lover are. If you like your lover
to wear silk, say so-- hopefully they'll enjoy the suggestion. Leather, denim,
uniform clothing-- allow your imagination to run wild. A more outrageous suggestion
is period clothing, such as the 1920's, or the 1400's. And even further out,
one could suggest wearing masks to allow fantasy to run riot-- animal masks
are a popular item in this field.
