From your photo, the implants do appear to sit somewhat low with more fullness in the lower pole, so mild bottoming out is a reasonable concern. A photo alone cannot confirm how much the inframammary fold or implant pocket has stretched, but your surgeon's advice to use support is a common conservative first step when the change is mild and stable. An underwire bra can help support the breast and may reduce downward pressure on the lower pocket while you are wearing it. However, it does not truly repair bottoming out, tighten the capsule, or permanently move the implant back up. If the fold has stretched, a bra may slow additional stretching but it cannot reliably prevent progression by itself. At one year after surgery, the implants are usually in a fairly settled position. If the appearance is not changing and the bottoming out is slight, observation with a well-fitting supportive bra may be reasonable. Make sure the wire sits at your breast fold and does not dig into the incision or push the implant into an uncomfortable position. If you notice the implant moving lower, the nipple looking higher on the breast mound, increasing asymmetry, new discomfort, or a visible crease problem, you should be re-examined. Revision options can include tightening the lower pocket, reinforcing the fold with an internal bra technique or mesh/ADM in selected cases, and sometimes changing implant size or pocket position. I would continue follow-up with your surgeon and consider a second opinion from a board-certified plastic surgeon if you are unsure or feel it is progressing.
