text: In my opinion, it is totally personal choice what one will wear and not. If anyone feel comfortable with loose clothing or skin tight wearing, its completely the person's individual preference. There are also many people who love to go around without any clothing and there are also many culture where people wear full clothing without showing even any body part. While practicing Yoga, the practitioners need to wear comfortable dresses and some find the loose dresses comfortable though I think some leggings and t-shirts or tang top is more comfortable. The main thing should be focused on comfort.
