Everyone, how did it feel after breast fat grafting?

I am a woman in my 20s considering breast fat grafting. I am curious about how the shape and size of my breasts change after the surgery. In particular, I would like to know if there are any precautions I should take to ensure natural-looking results. I am also curious about care methods and necessary steps during the recovery period. Do any of you happen to have recommendations for trustworthy clinics? I would love to hear various opinions!
