Socks can be worn outside yoga pants, which is not necessary.
Generally speaking, the loose pants we used to wear, which are slightly elastic, knitted and cotton and linen, can be used as yoga pants. It is best to have drawstring for trousers, and the length can be adjusted freely as required. The movements of yoga are softer and larger. Clothes that are too close to the body are not good for the ductility of the action. Therefore, pants are mainly loose, casual, comfortable and natural. Wear loose and comfortable clothes, let the body move freely, avoid the restriction of the body and breathing, relax physically and mentally, feel comfortable, and enter the yoga state faster.
