Before hitting the gala, the sisters goofed around in the Balmain showroom. In an Instagram snap, Jenner is seen towering over Kardashian as she gazes into the camera. The 18-year-old model jokingly captioned the pic: "She looks up to ME #BalmainArmy."
Clad in an intricate top and leopard print skirt, Kardashian is noticeably shorter than her catwalking sister, who looks fierce in an olive-green pleated dress.
The siblings then joined Balmain creative director and good friend Olivier Rousteing and headed to the fete, where photographer Mario Testino shared a picture of Kardashian's famed derriere. Testino captioned the pic: "The unmistakable @KimKardashian at the #VogueParisFoundation #CoutureByTestino @VogueParis"
Jenner is in Paris walking in the shows at Couture Fashion Week; on July 8 she walked for Chanel.
