The stunning ladies all rocked slicked-back, high ponytails and barely-there make-up.
Kendall and Gigi’s turn on the runway came the day after they enjoyed a night out with Olivier in the French capital.
The stars looked sensational as they joined the designer ahead of his Paris Fashion Week show set.
Keeping up with the Kardashians star Kendall showed off her incredible figure in a striking all-black ensemble. The 19-year-old paired a black halterneck crop top featuring lace-up detailing with a sheer black floor-length skirt.
She accessorised with chic black strappy sandals, and carried her essentials in a black clutch bag. Her make-up was as eye-catching as her outfit, with the young model opting for dramatic winged eyeliner.
Meanwhile, fellow model and close friend Gigi also upped the style stakes, dazzling in one of Balmain’s notorious embellished bodycon dresses, opting for one in nude and green shades. The blonde beauty wore her hair slicked back into a super sleek ponytail and completed her ensemble with nude stilettos.
Kendall and Gigi were recently unveiled as the faces of Balmain x H&M, along with Jourdan Dunn and male models Hao Yun Xiang and Dudley O’Shaughnessy.
“When you love the Balmain world, you love the models that are part of it too,” said Olivier in a statement following the unveiling of the first campaign images of the high street collaboration. “Kendall, Gigi and Jourdan are my friends, and they are the perfect choice to star in the Balmain x H&M campaign.”
