How Many CC's to Go From a B Cup to a Full C / Small D Cup Look? (Photos)

I try not to discuss breast size in terms of 'cup'  There is no standard in the industry for bra sizing.  I have never seen a bra labeled large C or small D.  It is the visual result.  I have my patients bring in representative pictures and combine that with breast measurements to help choose the implant size. 

Based on what you have uploaded high 300's to low 400's should work well for you.
 

That size will most certainly get you into a D. You look narrow and may do best with high profile implants. You will definitely grab some attention. 300-350 cc should get you into a nice C and be a bit more "natural" looking.
