My friend had it done. She did it in two stages. The first one took her from an A is maybe a B, but the second stage took her to maybe a DD＋. I should have asked the size but I was so amazed after the second stage I forgot to ask. I remember after the second stage her breasts were hard for a bit till the body adjusted. Since it's real it feels more real than implants and at least 3-4 years later she still seems to have it all from what I can tell from her social media. We haven't spoken in a while so I don't really know.
I know some people have it done after a few years as the fat shrinks? or gets reabsorbed? Not really sure how it all works. But in the second stage after she had it done she was told not to wear a bra while things healed and they looked fantastic.
