You are tall (5'7") and slim (115 lbs.) with B-cup breast volume of your own. I agree with your request for a modest implant size to increase your breasts by one cup size, but disagree with your surgeon's recommendation for high profile implants, as well as recommended size in the 175-200cc range. I would estimate that your breast base dimension is at least 13-14cm in diameter (or more accurately, your planned submuscular implant pocket dimension). 175-200cc high profile silicone gel implants have a diameter of 9.3-9.7cm, nearly two inches narrower than what I would anticipate your base dimension to be. This would lead to a cleavage gap between your breasts of almost 4 inches! Even a push-up bra cannot overcome that wide of a intermammary distance! In short, too-narrow (high profile) implants would look silly, and I also believe they would fall short of adding the requested full cup size. Though the exact implant volume roughly equivalent to one cup size varies among plastic surgeons who make this estimation, I believe that for a woman with your tall petite anatomy, it will take about 225-250cc per side to add one cup size to the breast volume you presently have. Fortunately, implants in this size range are also slightly wider, though even moderate profile silicone implants are 11.7-12.2cm wide, much more suited to your breast base dimension to give you an appropriate narrower cleavage without the wide, flat cleavage look! If you want higher, rounder, wide-cleavage "Baywatch coconut" breasts that are a bit smaller than your stated goal, then go with the 175cc high profile implants. I believe these will look unnatural, and obviously augmented (poorly, IMHO). If you prefer a softer, more natural look that gives you a nice C-cup, you should ask your surgeon to use 250cc moderate profile silicone gel implants. Trust me, you won't be "too big," and your cleavage area will be much more narrow and attractive-looking nude, or in a bra or swim top!
