I'm almost positive that I ordered the large and received the XL. I haven't made a return because it's good enough, and I needed leggings, and frankly, I wasn't positive that a Large would solve the biggest issue i have with it.
pros:
extremely soft! stretchy, comfy, color true to picture.
cons:
it doesn't do much in the way of compression? Perhaps this is because I got an extra large instead of the large I ordered, but the material itself feels a bit thin. I'm not sure it would be able to do much compression at all. i'm of course willing to revise my opinion, but I certainly wouldn't spend more money or time on ordering another pair of leggings.
Anyway, it's not worth returning -- i'll wear these -- but i wouldn't purchase leggings from popflex again given this scenario.
