Hello and thank you for your question. First of all, every woman has a unique view of their body image and ideal shape. With respect to breast implants, I want to start off by telling you what I tell many of my patients: Do not focus on cc's or bra sizes as many women see their friend with "x" number of cc implants etc and think that they have an idea of what they want. There is a lot that goes into implant selection -- your breast volume, the amount of cleavage you want to achieve, your base width, your rib shape/projection, etc. Without seeing you and doing your measurements or having photos to assess your starting point, it is difficult to assess accurately your final breast size or shape. The other thing to consider is that most women are not accurately sized for their bras. Different bra companies are sized differently and employees at various clothing stores will not use the same criteria to measure one's bra size.The most important thing to consider is really the size and look that is appealing to YOU with the implants you choose. Many surgeons have sizing models whether using bras with implants or computer simulation. I encourage you to discuss with your surgeon many of these considerations when deciding which implant and size to use during your surgery. Additionally, a breast implant is a round object and has a certain diameter. Your base width on each side of your chest will determine "how big of a ball" or what diameter implant you can reliably go up to with a socially acceptable cosmetic outcome. The implant will "augment" or increase the size of your breasts to an amount acceptable to you and your surgeon. My patients will try on a sports bra and then we pick the implants based on their measured breast base width. I have them try on implants of different sizes up to this maximum allowed size. Once they find a size that they like, they can even put their favorite T-shirt or shirt over the anticipated bra with implants. This helps my patients choose the shape that is most appealing to them. Remember, pick the implant that makes YOU the happiest. In reality, don't stress too much as this is the fun part of the process. =) Go with what is acceptable based on your measurements and makes you happiest and make sure to weigh the pros and cons of the options you are considering. It is a good thing that you are doing your research before making a final decision. When the appropriate steps are taken similar to above with a board certified plastic surgeon, most women experience very high satisfaction rates with breast augmentation. I hope this helps answer your question!
