Going to return and try to get a refund.
On receiving these a day ago I realized that these undies are really made from a heavy material (Bamboo is not heavy) and not anything like the light ones I saw the models wearing in the Add. As soon as I opened the product I saw that these would not suit me at all even though the size was OK (Medium) I am 5'6" tall and 60kilos (average). Anyway they are so very tight around the waist and loose around my upper thighs. I was taken in by the slick Add for this product - And what is the replacement Pads design about with a clip on thingy under undies? - I am going to return and see what happens because I am never going to go out in public wearing these ugly (thick) knickers.
