The three women depicted in the Over The Top link are not gross due to their large breasts, or anything else.

If they've had that done cosmetically to draw attention to themselves, they have certainly succeeded (I originally typed "exceeded" instead of succeeded - as some sort of Freudian typo perhaps).

In any case I sympathize with them. It would seem to me that the extra weight above the waist might cause other physical ailments, such as back problems, but I'm not a doctor. They seem not to care a whit for sympathy in the photo, however. They appear happy and content.

And big breasts or no, they are attractive women.
