For your pole dance class, you will need shorts and a t-shirt. Shorts should be above the knee because you use the skin on your legs to grip the pole. Fabric will slide right off the pole, giving you no grip. You can also wear trainers or leg warmers during the warm up and cool down. There should be no hand or wrist jewelry. To avoid making the pole slippery, do not apply any cream or lotions on your body the day of your pole dance class.
For your flexibility class, you will need any comfortable cloths, for example, yoga attire, trainers, leggings, leg warmers, etc.
