Will 540cc Get Me to a DD Cup? (Photos)

It is too early to tell, but I imagine that you will be very large.  At your height and weight, any implant over 500 cc's is a large implant.  I would encourage you not to "fixate" too much on your final size.  As you know, different bras from different designers have variable cup sizes.  While you may be a DD in one specific bra, another type of  bra with a D cup may fit you.  Try to enjoy your overall shape, size, and look--rather than only worry about whether you will have a DD.   Good luck.

Breast revision surgery is more difficult, complicated, and requires more time than primary surgery. There is as much as a 40% chance additional surgery will be needed following the #revision. As far as sizing, there are no promise or guarantee of the specific cup/bra #size and shape you will be after your surgery.  Implants which are under the muscle or are placed in a new position under the muscle may change with shape on muscle contracture and may have “#banding” and motion of the implants with muscle contracture. If this is unsatisfactory, it may require additional surgery which will also require additional surgeon’s fees, operating room and anesthetic fees.

It is very important to communicate your size goals with your surgeon.  In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or “C cup” or "fake looking" 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 press 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.
