Why ARE women's figures getting so much fuller?

With their dark hair, strong noses and refined chins, it is immediately apparent that women of the Clark family are related. Each is a feature that has been passed through the generations, and will no doubt appear in their children and children's children for years to come.
But there is one part of their bodies that does not appear to have been handed down the family line: their breasts.

"I love having big breasts. When I get dressed up to go out in the evenings, I make the most of it. It makes for a great neckline and my friends associate me with my big chest. I wouldn't want to be known any other way."

._. That's so weird to me... but I really don't get it. With my family, it's a little different. My maternal grandmother is "medium" and my mother is "big" and I am "small". So it doesn't make any sense whatsoever. But I think it has to do with diet, maybe? I was raised on the food my mum was raised on, basically... but I think I have eaten healthier than my mum. I think it's hormones in milk. I never really liked milk...
