But thongs aren't the only things Kendall's selling for the brand. In a video for their Original Sexy campaign, she models a bra as well alongside Joan Smalls, Isabeli Fontana and Edita Vilkeviciute.
Kendall, who's currently cat walking in Paris Fashion Week shows, hasn't been shy about baring her body, even if it's not in a major ad campaign. She Instagrammed a candid shot of herself in undies for Independence Day. We can't blame her...if you got it, flaunt it!
