What Size Do You Recommend to Get a Natural Look, 230cc or 280cc? (photo)

Unfortunately, there is no direct correlation between  the size of breast implants  and the resulting cup size.
In planning your breast augmentation procedure it will be very important to communicate your size goals with your surgeon.  in my practice I find the use of goal pictures to be very helpful.  in your case you could use your own before breast-feeding pictures as the goal. I have found that the use of words such as “natural” or “C cup” or "fake looking" or "top heavy" means different things to different people and therefore prove unhelpful.
 

Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup  size may also be inaccurate.


I use  intraoperative sizers and place the patient in the upright position to evaluate breast size. Use of these sizers also allow me to select the breast implant profile (low, moderate, moderate plus, high-profile) that would most likely achieve the patient's goals. The patient's goal pictures are hanging on the wall, and allow for direct comparison.
I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible. 
By the way, the most common regret after this operation, is “I wish I was bigger”.

I hope this helps.

There is not a large enough difference in the implant volumes you have chosen to make one a bad choice and the other a good choice.  In my practice, I base the implant choice on factors such as breast width, breast shape and volume, and what size the patient desires.  Intraoperatively, the use of implant sizers allows me to choose the best implant to meet the patient's goal for size as long as the breast shape remains natural.   I recommend that you review pictures with your plastic surgeon to determine your goals, then allow your plastic surgeon to make the decisions intraoperatively as to the best implant size to use.
