Good luck with that, Ajrt. I've been barking up that tree for a while and discussed it in the forums, and the consensus seems to be that the mainstream polewear providers (Mika, Bad Kitty, bodybinds, etc) don't take us larger girls into consideration. Finding something that fits, provides support, gives adequate coverage, and is as cute as what the skinny-mini dancers get to wear...next to impossible. You can get some of those qualities, but not the whole package. I've resorted to wearing less-than-ideal tops over my sports bras for at least *some* sense of cuteness.
This is bitter of me to say but it often feels like the clothing industry is repulsed by the idea of bigger ladies being sexy and outright refuses to service us. OR they offer a larger size of a cute bra/top without giving any thought to support, which to me is like paying lip service. "Yeah, we hear your complaints, here's the best we can do, deal with it. If it doesn't work... well, too bad for you I guess, maybe you should be smaller."
There's an enormous business opportunity here for the right person.
