I purchased two pair as a "buy one, get the other 50% off" promotion. When they arrived, I tried on one pair, seemed to fit, but I only had it on long enough to ensure it the right size. I followed the directions and washed them before wearing. Within minutes of wearing one, I started yanking on them trying to pull them up. It was low in the back and felt like it was falling down. The overall construction felt poor. After three hours I couldn't stand it anymore and took it off. Now I am stuck with both pairs because they cannot be returned if worn or washed. I will likely not buy online again unless I know for sure that the model number fits properly! Very disappointed that I wasted my money on this item.
