From the photos provided, it looks like you have a nice result; smooth with no big depression or lumps. Unless I am missing something on the photos, I would wait 6 months and re-assess your result with your plastic surgeon.
If it's been over a year and you still have excess puffiness of your breasts, then it is possible that you have had a recurrence of your breast tissue, you may need more fat removed via liposuction, and/or you may need some excess skin (that is not retracting) removed. Best to see...
Hi. Your breasts will change for at least 3 months after the operation
(sometimes up to 12 months, although this is unusual). Often things swell a little more once you return to exercise and full activity. Try to be patient at this stage and
wait until all the postoperative changes have finished...
