For yoga, wear light clothing that is comfortable. Leave watches, jewelry, socks, legwarmers and scarves in your yoga bag, as they hinder the exercise by getting in the way.
Wear cotton clothing or quick-drying athletic gear that bares arms and ankles. Both materials absorb sweat, allowing the body to breather easier, and showing more skin lets the instructor assist with your posture and alignment during the class. The clothing should also be fitted to offer support and allow for easier yoga movements. Do not wear street clothes or shoes, as this can affect the calm environment yoga studios strive to provide.
