I think I have been to the Rosin Box in Philadelphia.  I bought a capezio tank unitard there.  There was an older gentleman working there at the time -- this was about 12 years ago.

Regarding dancewear store experiences, I used to go to a place in Norfolk, VA that was great.  The owner was a woman (mid thirties) who always wanted to see how things looked on me.  I used to buy a lot of stuff there because she was so cool.  I was looking for a black leotard one time; she didn't have any men's leotards so she suggested a woman's.  She handed me a black, long sleeve, turtleneck leotard and told me to try it on.  She told me to come out so she could take a look.  I walked out and she said, "It fits you perfectly."  She adjusted the leotard around my butt a little and said, "That looks nice."  One other time I was trying on men's unitards.  Again, I modeled them for her.  Very cool woman.

I also love talking about tights, leotards and ballet.  My email is mmatthys2@aol.com.
