How Many Cc's Do I Need to Be a C-cup? (photo)

I always recommend one or two sizes higher than your chosen. So 325 or 350 cc high profile would be my recommendation to answer your question very directly. 

From your photos, it appears that you are in the range of a C cup. And for reference, a 38B is the same as a 36C so that you likely are in the range you requested. You should not judge your surgical results by the size of your bra, rather how you look in the mirror and if that was your ultimate goal. Bra sizing is no where near an exact or consistent science. 

Best of luck,

A 38B is equivalent to a 36C.  A 300 cc augment should increase you by at least a cup size.  Having been swollen, you became accustomed to a larger look than you requested preoperatively.  If you remain unhappy, three months down the road, you could consider a reaugment with larger implants but I would encourage you to take a look at your preop photos being jumping to conclusions.

There are no fixed standards for cup size.  Many of my patients have B's C's and D's in their bra drawer all (or occasionally none) of which fit. 

A B cup on a 36 inch band is larger than a B cup on a 34 inch band, and smaller than a B cup on a 38 inch band. I cannot imagine why your measurement went from 36 to 38. That measurement is based upon the diameter of the chest at the level of the breast fold, and that should not have changed with implants. 

The sizing discrepancy may well be due to that. The B cup on the 38 is larger than the B cup on the 36. It can be a full cup size or more.

Usually a 200 cc implant will give a one cup size increase. 

Thanks for your question, best wishes. 

Usually an increase in cup size requires about 200 cc's extrea in volume sometimes a bit more and sometiems a bit less.
