325 cc is not an unreasonable size, but trying on sizers in the office will give you the best idea. Picking the profile or style should be easily navigated by your plastic surgeon. Find a plastic surgeon with ELITE credentials who performs hundreds of breast augmentations each year. Then look at the plastic surgeon's website before and after photo galleries to get a sense of who can deliver the results. Kenneth Hughes, MD Los Angeles, CA
In order to know what size implant to use, your chest and breast measurements need to be evaluated. Also, it is important to understand what kind of look you are seeking. Frequently, I see patients seeking breast augmentation that are models or dancers that desire a look which gives them upper pole breast fullness. This would require a different style of implant than someone seeking a very natural look which simply allows them to look better in a strapless gown etc. It is also very important to appreciate the shape or your body and waist since the width of the implant can contribute to creating a more of an hour glass look if that is what is desired. So, in short, there are many factors that should be considered when picking an implant not just the cc volume.
