70c breast fat transplant

I'm thinking about getting a breast augmentation before summer this year, and I'm curious what everyone thinks! My breasts aren't cliffy at all, but they hang down a bit so I can see some ribs on top. The bra is also a bit empty at the top, so I can't wear bikinis or tight-fitting clothes with confidence ㅠㅜ Also, do I have bird breasts? My breasts point outward so I can see the cleavage well. If it doesn't come out
 , will it be effective? It would be nice if fat grafting at least 100 cc would be maintained, but I'm sad to see many reviews saying that 100% of the transplanted fat is lost ㅠㅠㅠ It's a bit difficult to put 100 cc implants in,, but I think fat grafting is good because you can achieve liposuction. Abdominal and lower body obesity isn't the only problem.
