There's a lot of latitude in dancewear these days, not like theold black-tights-&-white-T-shirt days. Still, I think most teach-ers would draw the line at seamed fishnet tights, even now & evenon women. The problem is that ballet classes are a lot of damnedhard work, & dancers (& teachers) don't have much patience withpeople taking ballet for the sake of a fetish. And in fact ifyou're working as hard as you should, you will forget what you'rewearing.
> Are there ballet classes for crossdressers
Unless you count something like the Trocks' company class, notthat I've heard of, & living in New York I've heard of plenty.
My guess: Your best bet is probably to locate other balleticallyinclined crossdressers & get together and have dancewear partiesin the privacy of your own home. You might even spring for one ofthose portable barres they advertise in the magazines. But don'texpect much patience from serious dancers. Even from seriousadult recreational dancers.
