When it comes to size, the difference between cup size and CCs is one of the most confusing factors of a conversation around breast augmentation. They say beauty is in the eye of the beholder. Well, the same is true of cup size. There is no standard measurement between bra manufacturers, so one manufacturer's D cup could be another manufacturer's DD. For this reason, your board certified plastic surgeon will discuss the size of your implants with you in CCs, not cup size. The most important part of determining what size is best for you is your overall body type and the characteristics of your frame. The shape of your ribcage, the distance between your natural breasts, and the amount of breast tissue you have to work with will all be determining factors in making the final decision about how large your augmented breasts will be. Dr. Bierly does not buy into a "one-size-fits-all" mentality when it comes to breast augmentation. Your augmentation will be as unique as you are and should be addressed with a great deal of care.
