What should I wear to class?

Think casual and comfortable whatever you feel good in.  Most students wear jeans or slacks.  Wear clothes that allow for freedom of movement.  Also, once you get moving, the studio can get quite warm.  Consider wearing a lightweight sweater that can be removed if you get too warm.  Avoid wearing blazers, or heavy sweaters as they can get in the way of your partner and affect your ability to move freely.
