Glamour, glitz, gowns and CLEAVAGE!

Female celebs pull out all the stops on Oscar night. And if you don't have a gold statue to tote around at the after-parties, a sure-fire way to get noticed is to sport some major cleavage.

 "Mad Men"'s curvaceous beauty Christina Hendricks, who attended Elton John's Oscar bash went up against Miss Mimi herself, music diva Mariah Carey.

Mariah wore a cobalt blue gown to frame her bodacious assets and Christina played up her luscious bosom with a black gown.

We applaud both these beauties for their ample assets.

But in the Dish Rag's cut-throat Breast-Dressed Battle, who wins?
