Want to achieve a D/DD - trying to decide between 315cc and 375cc?

At size 32 or 34, each 100 cc of implant corresponds to 1 cup size change. At size 36 or 38, each 200 cc of implant corresponds to 1 cup size change. From this, you can compute the volume required to achieve your desired goal.

Thank you for your question and pictures! Deciding on implant sizes is more complex than it seems. What you're asking depends on your anatomy as well as your body type. It also depends on the type of implant you pick. It is imperative that you have a proper assessment in your consultation to discuss your overall goals and where you can be fitted properly. There you will discuss the type of implant and size that fits you!

I would recommend that you see a board-certified plastic surgeon in your area that is a member of both ASPS & ASAPS. Go over your concerns with them and make sure above all,you walk out of there with several options and an idea of the pros and cons to each of them as well as realistic expectations.

It's important to obtain an understanding of how breast implant sizing and bra sizing works. There are two issues with asking a question like this. The first issue is that without actually measuring your breasts, seeing the amount of existing tissue you have, and discussing your aesthetic goals, there is no way to determine which implant size is best suited to you, or what kind of size a certain implant type will produce. 315cc on one patient can be very subtle, and on another patient can be very enhanced, it is all dependent on their anatomy. The second issue is that bra sizing is extremely variable. A D cup in one bra brand can be a C or a DD in another brand. As such, we never recommend speaking in terms of cup sizes. A better approach is to bring in inspiration photos to your plastic surgeon. Photos of results you like can help communicate your expectations to your plastic surgeon more clearly. This also provides a more specific view of which aspects you prefer whether it be cleavage, upper-pole fullness etc.

After I measure and discuss goals with my patients, we then look at pictures of women (my patients) with similar measurements with different size and style breast implants, and they choose what looks right for them. They also get to see what they would look like when the breasts have fully dropped and fluffed and in clothes. You get to see actual results and the surgeon's experience and not a virtual idea of what can be achieved. Women tell me that this process is very helpful in determining what size and style breast implant is right for them. Dr. Ted Eisenberg, Board Certified Plastic Surgeon and Author.

Dear abercrombie1,
breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.

More information is needed to help you determine the recommended implant for you. I encourage you to visit with a board certified plastic surgeon near you. Measurements will be taken of your breasts. This information will be combined with your surgical goals to help determine the right implant for you. In addition to volume, your surgeon will also consider style, type, and projection.

The breast cup size varies with your bra size. A D cup on a thin women is smaller than a D cup on a full figured women. For you, a cup is approximately 150 cc's. I believe you would need an implant over 400 cc's to be a D/DD. Many plastic surgeons have sizers to try on to simulate your new breast size. A consultation and examination is required to see if your anatomy can accommodate a large implant. Good luck!

The best way for you to know what size you will be is to actually try on both sizes to see what you like. This can be done during the consultation.

Hi and welcome to our forum!
Bra cup sizing is an extremely inaccurate method of determining breast size. There are no industry standards. One brand's "C" cup is another's "D" cup. In medicine, we use the metric system.
The following is not extremely accurate:
An A cup is approximately 235 cc volume. Adding 315 cc will make you a "C" cup (550 cc).
Adding 375 cc will make you a "C+" (610 cc).
A "D" cup would require an implant of approximately 525 cc volume.
The base width diameter of the implant chosen (implant footprint on the chest wall) should be approximately the same diameter as the width of your breast.
Best wishes...
