Combined with a shiny black one-shoulder dress and flawless makeup, she was a total throwback, and we just had to ask the "Keeping Up With the Kardashians" star where the inspiration for this upscale look came from.
"I love old Hollywood actresses like Ava Gardner and Audrey Hepburn," she said.
"There's so many different people that I channel, depending on the look that I feel like I'm going for."
And about that makeup. We asked the flawless-faced Kim what products she loves.
"I love a good concealor – YSL is great," she said. "I love a mascara that's by Anastacia, the eyebrow lady, that's pretty amazing. She has the best mascara."
Kim also revealed that she gets her famous glow using blush by MAC and a matte bronzer by Smashbox.
