The photos show breast ptosis with the nipple/areola sitting low on the breast mound, so an implant alone may not give the lifted shape you are hoping for. A 650-800 cc implant is very large for many patients and can add weight, stretch the lower breast, increase bottoming-out risk, and make existing sagging more noticeable rather than correcting it. Whether you can avoid a lift depends on your nipple position, breast base width, skin quality, and the look you would accept. Some patients choose an implant-only approach understanding the tradeoff, but if the goal is higher, rounder breasts, a lift with or without implants is often the more predictable plan. I cannot recommend a specific doctor here, but look for a board-certified plastic surgeon who performs both breast lifts and augmentations so the recommendation is not limited to one option.
