Best materials for pole clothes?

I've been searching for some bottoms to pole in and while I would loooove to own things from Bad Kitty, Mika and such, I'm a cheap ass and I just can't bring myself to spend too much on tiny pieces of clothing. :P So, I'm wondering what materials would be best specifically for poling and what does the material do (moisture wicking, stretchy, etc)? Any recommendations would be great too! :)
