I ordered two pairs for my sister and one pair for myself. They arrived in perfect condition and in a timely fashion. However, my sister told me she wanted me to exchange them for a different size. The seller only had instructions for returns and never responded to my e-mail inquiring about exchanging. I had no option but to send the tights back and hope for the best. The new tights came two or three days later. The quality of the tights is fantastic and they are very comfortable. I have nothing against the tights; just be 100% poitive in the size that you order.
