Kim Kardashian and Kendall Jenner Twin in Body-Hugging Black Gowns in Vegas

Kim Kardashian; Kendall Jenner

Call it sisters intuition, but Kim Kardashian and Kendall Jenner were definitely on the same page with their fashion choices this week.

The two reality stars both pulled out all the stops in terms of style as they attended the star-studded Grand Opening of Fontainebleau Las Vegas in Sin City on Wednesday, Dec. 13—and we couldn't help but notice some similarities in each of their outfits for the evening.

Starting with Kim, the 43-year-old mom of four stepped out in a form-fitting black gown made from a textured fabric and featuring a ruffled seem going down her side.

She kept with her usual glam for the outing, sporting a dewy makeup look with a nude lip while her dark locks draped down her back. The SKIMS founder also added a couple chunky rings and a simple chain necklace for accessories.

As for Kendall, the 28-year-old supermodel also opted for a fitted black number, with her midi-length gown for the evening featuring ultra-thin halter straps, a deep draped neckline and a body-hugging corset bodice.

The 818 founder added a pair of strappy black heels to the look, as well as a sparkly sequin bag thrown over one shoulder.

The sister duo is just two members of the famous Kardashian-Jenner family, made up of Kris Jenner's four children with ex-husband Robert Kardashian: Kourtney, 44, Kim, 43, Khloé , 39, and Rob, 36—as well as her two kids with ex Caitlyn Jenner: Kendall and Kylie, 26.

But Kim and Kendall weren't the only big names in attendance on Wednesday evening, as the Las Vegas event also hosted several A-listers, including Sylvester Stallone, Bryan Cranston, Paul Anka, Keith Urban, and Eva Longoria, just to name a few.
