Yoga clothing does not need to be a fashion statement although many who practice yoga like to wear fashionable yoga clothing to their classes. Other people do their yoga at home so their clothing for a yoga session is not seen by anyone including the instructor who is usually on a television screen.
Yoga is a series of poses or asanas that come from a practice started in ancient times by members of the Hindu religion. These yoga positions are designed to stretch the body for maximum flexibility and serenity. The yoga clothing should be designed to help each student execute the poses.
