Based on the photos, your breasts already sit quite close in the center, with a narrow space between them and visible medial fullness. More cleavage is not simply a matter of moving implants closer together; it depends on your chest wall, natural breast footprint, implant width/profile, skin envelope, and how the implant pocket was created. Trying to push the implants too far toward the midline can weaken the central support and may increase the risk of symmastia, sometimes called a "uni-boob," which is much harder to correct than a small gap. If you feel they are too close, the opposite approach may be needed, such as evaluating the pocket and possibly tightening the medial pocket or choosing a different implant plan in revision. For a fuller cleavage look without creating an unsafe pocket, a supportive bra, careful implant selection, or in selected cases small-volume fat grafting may help. The best next step is an in-person exam with a board-certified plastic surgeon who can assess your implant position, tissue thickness, and whether revision would improve the shape safely.
