Which one of my breast is in the right position?
Would like to see a before posted photo of your breasts before commenting. My early guess is the right looks more normal.???
Optimal breast implant position
The photos appear to show that the upper half of the breasts appear even, but there is a difference in the bottom half suggesting some pre-existing asymmetry. However, the one with more roundness on the bottom appears more natural to me in terms of breast shape. Wait until at least 6 months post op.
Breast asymmetry is normal, nobody is perfectly symmetrical. In your situation which breasts is 'correct' depends on what you looked like before. Your right may have been sitting slightly higher before surgery.
To improve your symmetry, you could either lift the left one or lower the right one. So the more appropriate question is which side do you like better?
