How Do You Figure Out The Relationship Between Breast Implant Volume and Bra Cup Size?
Q: I originally had breast augmentation three years ago and went from an A cup to a C cup. I got 375cc implant in now. I have decided that I would like to be bigger, at least another cup size. How do I know what next breast implant size to go to. My current plastic surgeon suggested 450cc but I am not sure. Is that enough of a size increase to get what I want?
A: There are a lot of variables that impact how a certain breast implant volume will look on any woman’s chest. There is no direct scale or measurement that can accurately predict for all women the correlation between breast implant volume and bra cup size.
That being said, you have one advantage over someone who is getting their initial breast augmentation. You know what cup size resulted from a specific volume. This does make it a little easier to predict what would happen with the next implant change as it is largely a matter of mathematics and proportionate relationships.
Going from 375cc to 450cc is a change of 75ccs or 20%. Based in your prior experience, it took 375cc to get a two cup size increase or roughly 175cc per each cup size increase. This would suggest then that a 75cc increase would only change your bra size by about a ½ cup size. To get a full cup size increase, it will take at least a volume increase of 125cc or a 33% increase in implant volume.
