I am sorry to hear about the problem you are experiencing. It is difficult to give you specific advice based on the clothed photographs but generally speaking, "repositioning" a breast implant involves manipulation of the breast implant capsules and/or surrounding tissues. For example, if a breast implant is sitting too high, "releasing" the lower breast implant capsule (scar tissue) may allow for more appropriate positioning of the breast implant on your chest wall. If the capsule surrounding the breast implant is abnormally thick ( encapsulation), removal of some capsule tissue may be indicated. Again, much will depend on your physical examination. Select your plastic surgeon carefully; careful physical examination and careful communication of your goals will be important. You may find the attached link, dedicated to revisionary breast surgery concerns, helpful to you as you learn more. Best wishes for an outcome that you will be pleased with long-term.
