In the March issue of Vogue , features director Giles Hattersley profiles the most famous sister act the world: Gigi and Bella Hadid .

The sisters had already shot their dual covers – and headline-grabbing nude portrait - for the March fashion special the previous month, but had reconvened for the day to take part in a clay sculpting challenge for a Vogue video .

Outside a thick snowstorm had enveloped Manhattan, as Bella headed off for her moment in front of the camera, while Gigi first flopped down on a sofa in a quiet corner to talk family, career, sisterhood, nudity and Zayn.

Gigi: I guess, mostly at the farm [in California], which we love because we can just walk out without wearing makeup and without getting dressed up, and go ride our horses or just hang out and watch The Food Network .

At this point Bella comes over, proudly sporting a pair of bright white Balenciaga Triple S Trainers, and flops down on top of Gigi.
