I would also recommend bare feet. If you must wear shoes to be comfortable-you can safely dance in any of the following available at dance supply places:
~Hermes dance sandals
I would also recommend that harem pants or skirts NOT be worn by beginners. I always stress this as well in my classes. FOr performances, yes-but the instructor needs to fully see your posture and positioning-and it is hard to correct someone if you can't see what they are doing wrong.
Also-you don't have to bare your belly. If you want to wear a snug fitting yoga tank, or leotard top or something that is great. You don't really want to wear a huge t-shirt-because there is a lot of chest, back, abdominal, and hip movements going on-and the instructor needs to see what you are doing, and if you are moving correctly.
A scarf is optional totally.
Any other questions you have, I would be happy to help you.
