The women probably didn't know if you were serious, or just curious. Beleive me, once you get serious about ballet, and show them that you're there to learn, sweat and strain, then they'll accept you as a fellow dancer.
I started taking ballet lessons at age 46. I to was concerned about being accepted, and wearing those darned tights. But after a while, I got over my fears, and have never felt better about my body!!
Go for it!!! [/i]
