Current Breast Volume is About 50cc (32a). If I Add 315cc, Would That Take Me to a Averge C Cup?

t's hard to tell without photos. also, cup size can be quite subjective.  I think that size implant will probably make you a small C cup and might suggest one size larger for an average C.

Cup sizes are very challenging to correlate with implant volume. As you have probably experienced when buying bras the cups sizes vary between department stores. On average 200 cc is about a cup size. The profile of the implant will have more impact on the volume of the breast above the nipple with the higher profile devices giving more upper pole fullness.

I decide on breast implant volume by measuring your breast and matching the appropriate implant to you. The profile is determined by the look you are trying to achieve.

Seek out a board certified plastic surgeon to evaluate you and discuss the appropriate choices to help you achieve the look you desire.

If the nipple length is excessive a nipple reduction can be done at the time of breast augmentation. I hope this was helpful
