Needless to say, all the siblings stepped out in style. Kim wore a floor-length gold Alexander Wang gown, black choker and an unexpected lip ring, while Khloe and Kendall opted for short, figure-hugging gold and black mini-dresses. As for Kourtney, she chose a white gown and matching fur coat, and Kylie sported an all-sequin black jumpsuit.
While Kim highjacked Khloe's Snapchat at the time of the event to share a video her adorable 3-year-old daughter, North West, Khloe later posted a sweet pic of Kourtney's 2-year-old son at the party. "My Reign," she captioned the image of her nephew.
