It must be great to be friends with designer Olivier Rousteing. For the newest Balmain ad campaign, he recruited his famous supermodel friends and their siblings to model items from the Fall 2015 collection. And of course the Jenner girls were involved! It turns out that Kim Kardashian and Kanye West's Balmain campaign for spring 2015 inspired the family concept, which was shot by Mario Sorrenti.
