Looking at your preoperative photographs, you have breast and chest wall asymmetry with tight skin. Your results will be less natural than a woman with more breast tissue. Because of your anatomy, your breasts will be more projecting. If your goal is to be smaller, a smaller implant would be indicated. Realize that for each 100cc's, that is equivalent to approximately 1 cup size. 45cc's will not make a big difference in what you see.
