I bought a pair in advance for a trip to India and they were perfect. Light cotton and loose enough to breath in the Indian summer. I have ordered several more, in white and blue, because I live in Florida and they are perfect here also. I have never been a fan of leggings but these are looser than what I have seen.
I don't wear them with the shoes pictured, but with comfortable sandals and sneaks.
I should also mention that I shopped for leggings in India and found these to be the lightest and most comfortable.
