Not the size advertised, at least what I received. I followed Groupon's sizing chart and received a product so small I couldn't slide it up my legs. No refund and can't return. I'm typically a size 6 and ordered medium. Received what is probably a size 0 - 2. If you aren't a small person don't order these, they don't stretch properly. I don't think even if I ordered their largest size it would have fit.
Here's the thing. I like the cut and all of the colors they come with, but they definitely run small so get the size up. I got what I usually get when I go to Victoria Secret's but when I put them on, they started to pull apart at the seams. So yes, they run small. But they're very cute and I'm sure would be perfect to wear under tight clothing like leggings and slim fit dresses.
