500cc to 650cc hp silicone will make me about how big? PS said he recommend a 500cc to 650cc hp silicone implant. Told PS i wanted a small d, but feel like those numbers sound to big? I am 5 ft 2, 135 lbs, a 36b or so. Breastfed 2 children, and desire the upper pole I used to have being a full c, small d. bwd is 12, and I have more of a concave chest wall. Thanks!
