In terms of "breast implants gone wrong", the most common complaint for women is that they chose the wrong breast implant size. Over one-third of all subsequent surgeries are just to change the size of the implant. Recent innovations in breast sizers like the Purlz Breast Sizing System are aimed at helping a woman internalize the breast implant size decision through experience. By wearing various sizes prior to the surgery she gains a sense of what implant size is right for her.
