Was randomly flipping channels tonight between 9 & 10, came across some competition show called "The Winner Is" on NBC (I think). A trio of ladies were dressed in something like a cross between flight attendants and '40s USO girls, and they were all definitely busty as their outfits were designed to show some hefty cleavage. Unfortunately I don't know anything else, as I can't stand music competitions in any form so I flipped away shortly thereafter. I don't know if they won anything or will show up again or what, but if you can find the episode somewhere (maybe Hulu has it? They have several NBC shows) they're definitely busty enough to warrant watching.
