In a standard vinyasa yoga flow, you will lie on your stomach, spread your legs, and even spend some time upside down. That means choosing clothing where you’ll never stress about flashing the person on the mat behind you! Many people choose form-fitting, stretchy fabrics that stay in place even in headstands. No matter what you choose, skip anything with buttons, zippers, or hardware (including bras)! The skin on your back will thank you later.
