How many cc's change a cup size, I have 415cc now, which puts me in a c cup bra, I would like D or DD cup

In general anywhere from 150-250cc will increase your cup by one size but t’s very difficult to predict a specific cup size after breast augmentation. The answer depends partially on how large your breasts were before the operation and what size implants are being put in, but also what brand of bra. It takes more to go from a C to a D than it does from an A to a B and there is really no consistency anymore between what a “D” really is from one brand to another. The best way to judge is to try some sizers at a sizing session and see if they look right for your frame and whether they look like what you picture a D cup should look like on you rather than focus on what the actual letter in the new bras you eventually buy are. Hope that helps! 

Dear jdoll6589,Breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.Daniel Barrett, MD

Hello,

You simply can't answer your question with any accuracy at all. There is no formula equating implant volume to cup size, and although some might try, it is not consistent or accurate. The best way you can determine your aesthetic goal is using sizers in the mirror. This is much more important than a bra size anyway, right? Best of luck!
