Yes, I have worn these tights to yoga - but more importantly I've worn them EVERYWHERE. They're a perfect legging fabric - opaque, thick but not bulky, great quality, warm without being too hot AND DID I MENTION OPAQUE?! Curvy ladies, I am a 12/14 and I think we have all experienced "the sheen." You know - when your leggings are too tight/thin and you get that iridescent look that is your skin showing through? These leggings have none of that. I can comfortably wear shirts that don't TOTALLY cover my hips and butt - like tshirts!! - without any fear of the dreaded see-through butt effect you get from so many other leggings.
