Unless your breast skin "brassiere" is altered and shaped via incisions, breast implants only "fill" the breast "container" into which they are placed. Implants add volume only, but the shape is determined by your pre-operative anatomy. If you want perky or uplifted breasts, shaping incisions (breast lift) are required.Of course, many of the high, round "Baywatch coconuts" you see are not due to some special magic with implants, or particularly-skilled surgeon, but rather to capsular contracture, which is a sort of internal (abnormal) tightening that makes the breasts hard. Trust me, you may like this look, but you don't want the "feel."Larger implants may give you more "fill" and therefore more tightening of the skin, but skin always stretches and ages. You have a splendid result for the degree of breast ptosis you started with. BTW, high profile implants do NOT give more upper pole fullness, as you will frequently read here and elsewhere. These round implants have a narrow diameter (and more projection for implant volume), and once they drop, soften, and settle (which they all do unless capsular contracture is developed), they have a shorter height (vertical diameter) and MORE indentation below the collar bones--LESS upper pole fullness. The widest profile implants that fit your breast bases will give the highest vertical height, and the most upper pole fullness. HP implants only give more upper pole fullness before they drop!You are slim with a beautiful breast augmentation result. A good push-up bra will give you all the fullness superiorly you wish for. Undressed, you have the benefit of soft, natural breasts! Best wishes! Dr. Tholen
