I was a A cup and I my implants are 540cc saline under the muscle. What cup size am I ? (photos)

The best way to determine what size bra you wear is to go try them on.  Each maker will be different.  You may find some fit more comfortably than others.  Find the one that fits.

Every bra manufacturer is different (Victoria's secret is VASTLY different from a Bali or Maidenform!!) so just get fitted at a reputable department store and try on some different bras to figure out your size. Enjoy your new shape!!!

Congratulations.  There is no standardization of cup sizes, which varies among different manufacturers.  Try some out and you'll know your new "size."

There are no standards any more. The bra companies all have their own system. Find a bra shop that will fit you and ensure you are supported and comfortable. That becomes your cup size for that particular company.Stephen M. Davis, MD, FACSGren Hills Plastic Surgery

Congratulations on having undergone the breast augmentation procedure. Given the variability of cup sizes from one bra manufacturer to another, there is no way for your plastic surgeon or online consultants to accurately predict exactly what cup size you will end up wearing. You will find the cup sizes will vary from one bra manufacturer to another. Also, guidelines such as “200-250 cc will equal 1 cup size increase” are not accurate or reliable. Therefore, I ask my patients not to communicate their goals, or evaluate the outcome of breast augmentation surgery, based on achieving a specific cup size. Hopefully, you will be very pleased with the long-term outcome of the procedure performed, regardless of the (somewhat arbitrary) cup size achieved. Best wishes.

Going and getting fitted at a bra shop will give you the answer you are looking for. There are no fixed definitions of cup size, and the sizes are different for different bands (32, 34, etc.). All the best
