Gap of about 2-3 fingers after Breast Augmentation? How do they look?

Your results look very nice at this point.  The gap that you started with before surgery will generally remain after surgery as this is determined by the medial insertion of your muscle fibers.  I hope that helps!

Thank you for the question. It is not possible to provide you with an accurate assessment based on clothed photographs.
 Generally speaking, a patient's specific anatomy (for example, relatively wide space between the breasts) may limit how close the medial breast folds (cleavage) will be after breast augmentation surgery.   Also,  a patient's nipple/areola complex position must also be taken into account; keep in mind that the breast implants must be centered  appropriately under each nipple/areola complex. Otherwise, the nipple/areola complexes will seem off-center on each breast mound.
You may wish to review your concerns/questions with your plastic surgeon. Best wishes.

It looks like your surgeon did a nice job and you have a nice result. The gap distance will vary in each person depending on their anatomy and also how aggressively the surgeon divided the muscle fibers in the center of the chest.
