More stockings totally agree...
Possyble
sheer black,
sheer white or
sheer nude (and then all the fantasy that the directors like...) for the
"see throguh factor" wich is the basic turn on for this extremily common fetish that almost all men loves...

In case of pantyhose sheer in the gusset too (is the pussy-ass part of the pantyhose).
There is nothing more exciting that watch a pussy, asshole feet legs and ass through that transparent nylon fabric... it is so teasing, intriguing and super hot...
In my opinion would be great the high hills only at the beginning of the scene... then leave the feet to be descovered, still keeping the nylons on, but without the hills. So that we can appreciate also the the feet of the models...
