oh nice! I am also looking to return to Ballet and hopefully next season will join. My friend has found a good adult class (god they are rare... who thought of the idea of mixing aerobics with ballet and call it adult ballet classes????) In my previous class in another town we also had a few men joining us. It was lovely. The younger girls were a bit apprehensive of having a guy in class (well 16 years old teenagers are just well 16 year old teenagers ha!) but the rest was bring it on... there can be more!
that said. ballet is excellent to get posture and poise. It doesn't matter that you can not do a perfect pirouette or look like a flailing elephant when attempting a grand jeté. The thing that makes ballet so valuable as a hobby, is to look at yourself and improve improve improve.
HAVE FUN!
