I would do leather... not sure about latex outside of editorials though. Still, I don't get out enough to try something fancy and they definitely would not be appropriate for school! Hahaha oh dear imagine that.
i think girls can pull off this look more so than guys, but i think it takes a certain slim figure (i.e. those bodies that are not as curvy) to eccentuate the sleek sexy slim line the skinny leather pants create. As for latex, i am not a fan of it, i think it only belongs on the third leg.
I'm really loving this look. Maybe I can make a pair, but the pvc fabric might be hard to find. Might venture to the seedy part of town tonight and look for a pair at the sex shops.
the thing about latex versus leather is that you have to put it on with powder (which can be a bit messy) and it will make you sweat. leather breathes and is far more comfortable in the long run and you can buy patent if you want the shine.
