How Many CC's of Saline to Make Me a DD Cup? (photo)

If you are a 34 B, then each 100 cc's will be 1 cup size change.  To become a DD, you will need 300 cc's implants.  However, this also assumes that this amount can be placed underneath the pectoralis major muscle.

Thank you for the question and pictures.
Unfortunately,  no plastic surgeon is able to accurately predict what cup size you will end up wearing after breast augmentation with a certain size implant. I would suggest that you not base your communication  or your satisfaction with the results of surgery on achieving a specific cup size. 
I would also suggest that you communicate your goals clearly with your plastic surgeon ( I prefer the use of goal pictures)  and ask him/her to do his/her best to achieve the results you are looking for.  You may want to leave it up to him/her to use a breast implant that he/she feels will do the job based on intraoperative evaluation.
Again, the preoperative communication of goals is critical.  Once you feel comfortable that you have communicated your goals clearly ( assuming you have chosen your plastic surgeon carefully),  you will likely feel comfortable allowing him/her to choose the appropriate breast implants for you.
Best wishes.
