Fat grafting from thighs to cover rippling on breasts

Hi Community. It's been 12 days since I had my expanders replaced with implants. In 3 months, I will undergo a fat transfer from my thighs to my breasts to cover rippling and hollows. I am very thin everywhere except my thighs - family trait ;-), but my surgeon is concerned that it may not be enough fat. Has anyone had a fat graft using their thighs as the donor site. If so, how long is recovery, does it leave divots and hollows where it was removed?

Thanks!
