I subscribed to Splendies panties club and they had my size wrong for the first 2 months and you can not send them back for an exchange. Once I got the correct size I was very happy with the quality and comfort of these! So my loss is your gain!! 3 pairs Green Shamrock pair are made of 90%nylon and 10%spandex.
