I am 26 years old, no children. 5'7" 120lbs BWD 12, started out with 34 small B. I told my surgeon I wanted to be a small C-I wasn't concerned with looking full in clothing, mostly just swimsuits and strapless dresses. I wanted nothing huge. I decided on 339, bc I liked the 304 and everyone says to compensate for going under the muscle. (silicone) While in surgery he chose to put in 371. I feel huge!! Im still early but is there any way I will go down to a Small-mid C cup? My survey was June 15 2012. It's still early I know, but I have not been sized yet but if I had to guess a 34D at the moment.
