Breast Augmentation for Very Small Breasts and a Slim Frame – Can It Look Natural? (Photos)

Hello, I have very small breasts and a very slim body frame (photos attached), and I would like to know whether breast augmentation can look truly natural on someone with my anatomy. My biggest concern is that the implants could end up looking like two separate objects placed on my chest rather than natural breasts. I am not interested in a large augmentation. I would probably choose implants no larger than 300cc, teardrop-shaped, placed under the muscle, possibly combined with fat grafting to the upper pole for a softer and more natural transition. I also have a chest wall asymmetry above my left breast, where the rib/chest bone protrudes slightly outward. Because of this, I am wondering whether different implant sizes should be considered to improve overall symmetry. The surgeon I consulted with said that he would not recommend different sizes, but I would appreciate additional opinions. My goal is to achieve the most natural result possible—not too large, but not so small that the surgery makes little difference. What worries me most is excessive fullness in the upper pole, as that is usually what makes augmented breasts look obviously artificial to me. Based on my body type and chest anatomy, do you think a natural-looking result is realistically achievable? Would fat grafting help reduce the artificial appearance? And would you consider different implant sizes given the chest wall asymmetry, or is my surgeon's recommendation reasonable? Thank you very much for your advic
