It’s almost criminal to name names, because the very actresses whose body-mass indexes have been the subject of endless tabloid speculation are the very ones now sporting sexier curves. You could definitely see the difference if you concentrated solely on the upper arms. Instead of a Barbie-doll circumference, there was suddenly, amazingly, a womanly roundness to their frames. More Marilyn than Twiggy, that’s for sure.
