A lot of us have our signature accessories, but Olivia Munn has made a career out of her favorite wardrobe accoutrement: her cleavage.

The "Newsroom" actress hit up the 2012 Emmys after party on Sunday night in a Armani Prive Couture dress that even threatened to take the sexy dress watch off of Christina Hendricks and Kat Dennings. With her straightened jet black hair framing her face and her black dress framing her, well, you know, Munn, 32, must have had to move extra delicately to keep from having a serious wardrobe malfunction, right? (Although it wouldn't be the only one of the night.)

For those of you familiar with Olivia's decollete (read: all of us), the plunging neckline isn't a new look for her, but still: this Armani was two parts Katy Perry's epically cleavage-y purple dress, one part Morena Baccarin's plunging Basil Soda number, also from Emmys night.

Behold.
