Achievable breast size does not necessarily equate with achievable breast beauty.
Enlarged breasts are beautiful only if the shape is beautiful as well.
This is an important concept, because if the only goal is to achieve the largest conceivable breast size, there will be a point where the overall shape, and thus beauty of the breast is compromised. At the time of surgery I insert a temporary disposable breast implant sizer which is used to determine the largest implant size that still maintains a beautiful breast shape. I then use the permanent saline implants of the same volume, and make final adjustments to the pockets to maximize breast symmetry and shape.
