Overall I think it's quite funny to talk about "big" boobs when it comes to Carrie Fisher - she was minute of stature, as in very tiny, standing 5ft0.5in. "tall" - so both her boobs would fit in one of my palms (I'm 6ft3in) without problems, so big is not exactly the right word imo.
- She was nicely proportioned for her size, but her boobs wasn't big.
