Proper alignment of yoga postures is important for many types of yoga. Choose clothes that are not too baggy and that help you and your yoga instructor make sure you’re not doing anything harmful to your body. In more physical types of yoga and especially in hot classes, expect to sweat. Wear clothes that dry quickly, wick moisture away, and will keep you as comfortable as possible to get the most out of your yoga class. Fabrics with stretch will help you feel most comfortable as you move from pose to pose. Whatever you choose to wear to class, you should be able to move freely and feel good.
