You go girl! Well I think it is awesome for you to dance! I am 15 and I have been dancing since I was 3... But I love it when newer and older people join! As far as what to wear you may want to give your studio a call and just ask what they wear. I belong to 3 different studios... One is very serious and you have to wear certain color leos and tights, even cerain ballet slippers. The second is still serious however not so touchy about the specifics but they are cool and you just kinda have fun, and the third you can stroll up in your PJ's and they are happy to see you! So it depends on how serious your studio is...So just ask what their "uniform" is.Good Luck!!![/i]
