Bra size for 492 mL implant

You have asked an unanswerable question in this format.  Bra size is determined by the number of cc in your natural breast tissue plus the number of cc in the implant.  In addition it seems that almost every manufacturer has different bra sizes  mainly due to vanity sizing. As a rough estimate 100 to 200 mL increases your bra one cup size depending on your chest size.  The implant you were describing could increase your bra size by 2 to 3 cup sizes . Your best option is to see a board-certified plastic surgeon who is experienced and breast implant surgery and have an exam in a consultation. Best of luck to yoi

The right size for you

It is very difficult to determine the exact size and shape implant you will require to best match your ideal breast image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation surgery including different approaches, techniques and implant choices. This is because several measurements not to mention your breast characteristics are needed to determine the optimal implant size to obtain your goals. Without knowing these dimensions it would be difficult to make this determination. For example, the existing base width of your breast will determine, in many cases, the maximal volume per implant profile that you can accommodate. To illustrate; a 100 cc difference may make a significant difference with a narrow base width breast, but much less of a difference if you have a wide chest wall and wide breast “foot print”. Therefore, just because your friend may have a great result with let’s say a 350 cc implant to make her go from a “A” cup to a “C” cup size does not mean that you will have the same result with the same size implant. . Further simply placing implants in a bra to determine the size best for you is not always accurate as the bra often distorts the size, is dependent on the pressure the bra places plus the implant is outside your breast and not under it among other variables. Computer software morphing programs that automatically determine the best implant size can be helpful in some but not all cases (e.g. doesn’t work well in my experience with existing implants, sagging or asymmetric breasts). Using “want to be” photos however are useful if simply provided to the surgeon.

I appreciate your question. It depends on your chest wall measurements and existing breast tissue as implant size does not accurately correlate to a bra size.  It also depends on the brand and style of bra you wear as size varies from manufacturer to manufacturer. The best way to assess and give true advice would be an in-person exam. Please see a board-certified plastic surgeon that specializes in aesthetic and restorative breast surgery. Best of luck!

No, no one can say exactly what bra size 492 cc implant will give you since bras are not made to a specific sizes. Plus, the size will also depend upon how much tissue you have. However, that is a large implant and may increase your cup sizes from 2-3 sizes larger.

Thank you for your question.  Unfortunately it is impossible to correlate 492cc to a cup size as this will add to your current natural breast tissue and because each bra manufacturer uses different sizing measurements.  As a result it is best to find a sizer that best represents what you would like to accomplish and months after your procedure, be fitted with a supportive bra.  In essence fit your bra to your new breasts, not the other way around.  Hope this helps.

What bra size a 492 cc silicone implant will turn out to be?

Thank you for the question.  There is no accurate/reliable/predictable correlation between size/profile breast implant utilized and cup size achieved. In my opinion, I do not think that the generalizations of "150 cc or 200 cc equates to 1 cup" hold any validity or is helpful in any specific way. There are simply too many variables such as a specific patient's dimensions and the variability in bra manufacturer's cup sizes… 
  Ultimately, careful communication of your goals (in my practice I prefer the use of goal pictures, direct examination/communication in front of a full-length mirror, in bra sizers, and computer imaging) as well as careful measurements (dimensional planning) will be critical.
Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery ( regarding breast implant size/profile selection) is:1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. For example, I have found that the use of words such as “natural look” or "D cup" etc means different things to different people and therefore prove unhelpful.Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. Again, the use of computer imaging has been very helpful during the communication process, in our practice.3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, after the use of temporary intraoperative sizers.I hope this (and the attached link, dedicated to breast augmentation surgery concerns) helps. Best wishes for an outcome that you will be very pleased with.

The best cosmetic result in any particular breast augmentation patient depends on a variety of factors, including: your individual anatomy, realistic expectations, a thorough discussion with the plastic surgeon about the options, and an understanding of the pros and cons of any particular implant choice. Proper sizing is not just about the number of cc’s. The thickness of your tissue, breast dimensions which include the width, height, and projection, as well as chest wall width all need to be considered when choosing an implant. Trying on implant “sizers” of various shapes and volumes while wearing a tight t-shirt, bra, or bathing sit at a preoperative visit will help you and your surgeon choose the optimal implant. There are no manufacturers' standards for cup sizing in the bra industry.
The cups of a 32 D+ and a 38 D+ are significantly different. Cup size varies from manufacturer to manufacturer and even within styles from any particular manufacturer. 
Keep in mind that following the advice from a surgeon on this or any other website who proposes to tell you exactly what to do without examining you, physically feeling the tissue, assessing your desired outcome, taking a full medical history, and discussing the pros and cons of each operative procedure would not be in your best interest. I would suggest you find a plastic surgeon certified by the American Board of Plastic Surgery and ideally a member of the American Society for Aesthetic Plastic Surgery (ASAPS) that you trust and are comfortable with. You should discuss your concerns with that surgeon in person.
