I agree with the other responses here; it is impossible to say what kind of implant any woman has based on a photo. However, if you bring these photos with you to a consultation, you can discuss your goals with your surgeon. I recommend seeing a board certified plastic surgeon with a lot of breast augmentation experience. He or she will be comfortable with a wide array of implants to get you a specific look. One thing you might want to mention in a consultation is your preference for a "natural look" and if a moderate implant is a good choice for you. I am only saying this based on your words of "most realistic breast augmentation." Implants come in varying projections, and a moderate implant will give less upper pole fullness, and has a wider diameter. Of course, the ultimate decision will come after a thorough examination, breast measurements, and a lengthy discussion with your surgeon. Some people have too narrow of a chest wall to support a moderate implant. Trust your surgeon, communicate your goals, and you will be happy. Best of luck!
