I was a 32b and saggy and ended up a 32e cup!! not much difference to a 30e!. I had 340cc implants and uplift to achieve this size. Plus ive gained about 10lbs so now a 32f.
Im guessing if you had a 380cc you would prob end up a 30e, or even a 340 may do it. if you could get away with a 380-410 you wud def achieve this size XXXXX hope this helps, feel free to ask owt else XX
