How big is too Big?

Oh. Is it time for this one, again? Oh good....damnit...I can't find my old answer...I'll have to type a new one...

For me, it's all about the clothes bursting...then, beyond that, I think Tiffany Towers had the perfect sized boobs..so, what is that? Beach Balls? Basket Balls? Slightly overfilled volleyballs with professional lining?

Sorry...couldn't resist. Somewhere between "There's no WAY those are real" and "Room filling."
