Thanks for the photos. You have constricted breasts with minimized lower pole breast tissues, short distance between nipple and inframammary fold, and relatively high fold with sharp fold crease. On top of it, your areola are wide apart from each other. Additional information such as quality of breast skin and thickness of breast tissues will help finalize your treatment plan. For my patients who present with similar issues, the final treatment is almost always a set of compromises. It's important to figure out what's the most important issue for you. Is it certain size or shape? How important is cleavage? How far apart should the your breast implants be positioned? Are you willing to have excessive upper pole fullness? How about double bubble deformity?
My suggestion, just based on photos alone, would be periareolar incision, subfascial(above the muscle) placement, anatomical shaped texture silicone implant from Sientra. Low to mid 300's cc.
I would highly recommend that you seek out in person consultation with an experienced board certified plastic surgeon to work out the best treatment plan for you.
