Breast lift would be best

It is always difficult to render advice without an exam, but your picture does help. It appears that a mastopexy (or breast lift) is what may be needed to give you the look you desire.  In addition, the fold under the breast may also need to be raised.  This can be done at the same time as a breast lift and you can keep the same implants. The option of going to smaller implants also exists.  Unfortunately, I do not believe the look you desire is possible without scars. You would likely have scars around the areola, and then straight down to the fold.  The good news, however, is that you will likely get better appearing scars than if the lift was done concurrently with the breast augmentation. A consultation with a plastic surgeon should answer any other questions you may have. Take care.
