If you thought the booty battle was tough, get a load of this busty competition! Starting us off right, Kim draws gazes to her ample cleavage in a tight white crop paired with a form-fitting skirt for New York Fashion Week.
Khloe on the other hand, raised the stakes and flashed her braless cleavage in a white blouse.
Another chesty choice! Kim sports a mega-pushup bodice with a racy mesh skirt to bottom it out.
She's back with a plunging neckline! But this time, Khloe also gave us a glimpse of some major leg too, sporting a big slit in her little black dress.
Oo la la! Kimmy just kicked it up a notch.
But Khloe isn't far behind…
Even arriving at LAX is a competition. Kim brings it with her chest on full display.
Incoming! Khloe opts for casual cleavage – ample nonetheless – for her LAX travels.
Baby time? More like booby time.
Uh oh, Khloe's falling behind! Kim just blew her out of the water in this chic deep-V top.
Looks like Kim takes the cake! No one can resist that hot bod.
