For yoga pants, these are amazing: https://www.amazon.com/Spalding-Womens-Bootleg-Black-X-Large/dp/B005GYGG0S/ref=sr_1_4?crid=1WF37Z6R5HN08&dchild=1&keywords=spaulding%2Byoga%2Bpants%2Bfor%2Bwomen&qid=1571686962&sprefix=Spaulding%2Caps%2C225&sr=8-4&th=1
Stretch cotton. Not shiny or see-through. Very light compression in hips and thighs. They go all the way to 3x.
I’ve worn them for years. I wear them as regular work pants with longer shirts and tunics, too. I’ve had my current two pair for at least three years and they show no signs of wear. And I wear them a lot.
I’ve never tried their leggings, but now I’m tempted.
I also like Hue, Danskin, and Marika.
