What cup size is 430 /450cc?

It’s impossible to say what your final bra size will be because I don’t know if a 32DD is your correct bra size preop. Every bra fits differently thus you may be different cup sizes in different bras. If a 32DD is your correct bra size then I would imagine that 430cc-450cc implants would put you in the 32 DDD-G bra size which will be impossible to find except online. Implants of this size may not be a wise choice for someone of body size. I would strongly recommend speaking to a board-certified PS to get more info and an exam in person. You may also want to see several plastic surgeons for consults before you decide on a surgeon and implant size. Best wishes. 

It’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. There is really no consistency anymore between what a any given cup size really is from one brand to another. One woman may be a double d in one brand and a c in another. The best way to judge is to try the implants at your sizing session and see if they look right for your frame and whether they look like what you picture your desired cupsize should look like on you rather than focus on what the actual letter in the new bras you eventually buy are. Hope that helps!
