Kendall Jenner and Joan Smalls get down to their Calvins

In a move to trump all #mycalvins posts, Kendall Jenner, Joan Smalls, Edita Vilkeviciute and Isabeli Fontana have appeared in the latest global campaign for Calvin Klein Underwear, wearing nothing but.

Photographed by Mikael Jansson in New York, the signature black and white shots are based around the idea of 'the original sexy', a concept invoked by the natural, relaxed sensuality of the It-girls that feature.

Kendall, Joan, Edita and Isabeli join an alumni of Calvin Klein Underwear front women that includes Kate Moss, Christy Turlington, Lara Stone and Natalia Vodianova.

See the campaign below, and watch above as Kendall, et. al. prove why they're the original sexy.
