This question is one of the more challenging ones to answer. Typically, we tell patients that we do not guarantee a cup size but rather work to find an implant that will fit their body type and ideal aesthetic. The rule of thumb is that for a 36-inch chest, each 150cc will add one cup size. This, however, can vary based on skin laxity, skin quality, and implant firmness. Be sure to discuss your aesthetic goals with your board-certified plastic surgeon, and read our related blog post to learn about choosing the right implant for your lifestyle.
