Those who have unders (which are completely under the muscle) or partials (between the pectoral muscles) tend to have little or no breast tissue. They have this, as they would then achieve a more natural look, as they do not have enough tissue to cover the roundness of the implant. Therefore would most likely end up with a “stuck on” look, if they had overs. Your surgeon must have thought you had enough breast tissue to have overs. I have had overs because I had plenty of breast tissue and do a lot of upper body exercises. The healing time is shorter and when contracting my pectorals, my implant does not move upward with it. xx
