Vitty, I know of someone who had a tummy tuck and was totally pleased with the results for all the time that I knew her. Haven't seen her in about 25 yrs, though.
As for the breast enhancement surgery, the fat from the tummy seems that it would be the safest and most natural way to go. You could always decide on how much you wanted transplanted from tummy to boobies, eh?
