The pair both donned sheer 60s-style dresses, with hair and makeup also giving a nod to the era, featuring winged eyeliner and modern beehives.
But the pals didn't walk on your average runway. Rather, the presentation was made at the Grand Palais, which had been made to look like a French brasserie with red booths and bar stools.
According to the Daily Mail, the girls took a lap of the room before sitting at the bar at Brasserie Gabrielle at Grand Palais de Paris, where Karl's muse Baptiste Giabiconi was transformed into a barman.
Guests sat in booths around the bar and included Kendall's mum Kris Jenner, Anna Wintour, Mario Testino, Florence Welch and Poppy Delevingne, who looked stunning as she supported her sister Cara in a gold fringed Chanel minidress.
The clothes saw a mix of the traditional Chanel tweed, cocoon silhouettes, and ruffled collars and skirts that would surely make Keira Knightley's heart skip a beat.
There was a distinct 60s feel to the collection, with multi-coloured chevron-print fine knits, as well as monochrome babydoll dresses and low square-heeled shoes.
