A Fitness Model Torn Between 371 Cc and 450 Cc

The most important determination for choosing a size is the base diameter of the breast, which I presume your surgeon measured and told you that either of the sizes will fit. In general, the high profile implant will have more of the fake round look that you specifically said you don't want. The bigger implants are also more likely to sag and stretch the skin over time. Be very certain you are aware also of how placement of the implants under or over the muscle will affect your fitness activies and appearance in competitions. Under is more prone to animation deformities which are distortions when you flex, but over is likely to look more fake.

It is very difficult to determine which implant is best for you, but in my opinion I think the Allergan style 20 high profile implant is the best device. Based on your height and weight I would think an implant around 425 would be perfect. Remember, this is my opinion based only on your height and weight and my experience with my patients.  The style 20 implant provides for more upper pole fullness and stll maintains a natural look for most patients. Good luck! Work closely with your surgeon to find the right implant for you.
