Your photos show significant breast deflation with the nipple and lower breast sitting low on the chest. In that situation, implants can add volume, but they do not reliably lift the nipple or tighten loose skin. If implants are placed without a lift when the nipple is already low, the implant may sit higher on the chest while the natural breast tissue hangs lower over it. This can create a heavy or "waterfall" look rather than a round, centered breast shape. Choosing a larger implant to avoid a lift can also add weight and may worsen stretching over time. A lift is usually the procedure that repositions the nipple and reshapes the lower breast envelope. If you also want more volume, a lift with implants may be considered, either in one operation or sometimes staged depending on your tissue quality, implant size goals, and your surgeon's exam. The tradeoff is scar visibility, but the tradeoff of avoiding the lift may be a less predictable shape. An in-person exam is needed to confirm the best plan, but based on the degree of deflation and nipple position visible in the photos, I would expect a lift to be part of the discussion if your goal is a higher, more youthful breast shape.
