Depends on the class Id recommend calling a head of time. Some require specific attire such as a full gi with belt and others recommend rashguard/tight long sleeve and shorts etc. If they require gi etc they will usually sell them at the gym or tell you where you can buy what you need. Also a water bottle, open mind and sense of humblness that you are going to get tapped a lot. But don't worry you will get better, just relax try to get to know people and don't be afraid to ask questions and have fun.
