I'm a petite woman, 5'3 and 100lbs. I breastfed my youngest child for over a year. I am currently an A but sometimes can barely fit into that size. I am looking to achieve a C cup without looking top heavy, but I also don't want to regret going too small. A surgeon I had a consultation with suggested 300cc high profile silicone under the muscle, but I feel that may be too small (when my milk came in I went to a D cup and it fit proportionally) I was thinking more 325-50cc. What opinions do you ladies have? This website has helped me thus far and I can only hope to gain more info as I get closer to choosing a PS and actually getting my boobies!!
