The "Being Mary Jane" star looked positively stunning on the green-and-white carpet at the famed soirée in the unique, asymmetrical look. Half of her outfit was a classic black gown with an exaggerated shoulder, but the other half was simply a blue bralette and underwear combo connected by flowing extra fabric.

The fearless actress totally owned the sexy look that proved to be a definite show-stopper.

Union finished off her look with a chic, cropped 'do, dark eye makeup and strappy black heels. She also threw in some diamond jewelry for good measure.

She wasn't the only star to rock a risqué look at the party, though: Mariah Carey flashed major cleavage for the cameras, while future NBC News mainstay Megyn Kelly turned heads with a sexy thigh-high slit.
