Students have asked what to wear to yoga practice. Usually we wear something that is comfortable, loose enough to move but not too loose to fall off as we move. T shirts and tank tops are comfortable except sometimes the neck of the T shirt blocks the face/mouth during downward facing poses. Bigger shirts may also ride up during practice. Depending on where you practice, having a sweater or sweatshirt to start and finish your practice, before you warm up and during Savasana, may prevent chilling. Yoga pants come in 3 lengths, shorts, 3/4 length or full length. I prefer cotton blend with spandex as it is softer, but I do have polyester/spandex blend pants. I find the pants with the fold over tops do not stay up as well. The fold-over tops come in great patterns, but there is not enough tightness/conforming fit on the hips to hold them up. Leggings also work well for yoga but make sure they are not see-through! Leggings come in a variety of qualities. Some are snugger than others and stay up better. I bought a cotton blend pair at Walmart that are comfortable, not see-through, but not as snug and are thinner and shorter than other higher end pairs. Online you can find yoga pants that are very loose and wide. I have seen them called elephant pants. My favorite place to by yoga pants is Old Navy (in store or online). They have cotton blends and polyester blends in most styles. I have Old Navy yoga pants that are 4 years old! The prices are reasonable and the quality is great. I recently bought a pair of 3/4 length cotton blend yoga pants at Walmart and so far love them.
Men can where shorts and pants that are comfortable. Make sure your backside is covered during bending poses! Some of my male students have shown parts that should not be shown!!
Some folks like to wear socks. I tried some toe socks with made for yoga that had none slip material on the bottom. This pair came in general S-M-L sizes. The small fit, but I would have liked the socks be a bit snugger some my foot would not slide inside it. Someone gave me "maryjanes" made of lycra/polyester cloth with the no-slip bottom. They fit my feet better.
In the end, it is what you find comfortable!
What do you find comfortable for yoga practice?
I enjoy yoga as it brings peace to my life. Teaching yoga has brought joy to my life and given me a chance to encourage others in learning yoga.
