Ordered two pair of yoga pants that were advertised as 89% cotton. I was delighted as they are hard to find in cotton. I knew it would take a long time before they came--that's part of the deal. But when they arrived I saw they are half polyester and half spandex--NOT as advertised. In addition, they are nonreturnable. I'm going to give up on Zulily if they don't do something about this. I am not holding my breath.
