25F, 115lbs, 4'11 - Am I a good candidate for breast fat transfer? (Photos)

I have some issues with my breasts as they are currently. The primary isssue is the tissue above my breasts near my armpit. I am not sure if it is entirely fat, or if it is also some other kind of tissue like axial breast tissue or something. My secondary issue is that my breasts do not look particularly feminine, perky, full, normal etc. I believe this is in part because they are low rooted, somewhat saggy, and could simply use a little more tissue. Would breast fat transfer solve my issues? does the tissue above my breasts look like fat, and if so, could it be removed and put into my breasts to achieve the look Im hoping for? I ultimately just want a more normal appearing chest witj slightly fuller breasts. 25F, 115lbs, 4'11. 34" circumference directly under my armpits, above my breasts. 33" bustline circumference, 30" band circumference.
