Kendall Jenner and Gigi Hadid can make anything high-fashion. Longtime BFFs Jenner, 29, and Hadid, 30, posed together on the cover of Vogue for the magazine's October issue, which was published on Monday, September 8. In one shot, the catwalk icons saddled up to ride horses in flowy Alexander McQueen gowns. Jenner, for her part, stunned in a lavender design featuring a plunging neckline and ruffle details that lined her airy skirt. She teamed the look with Ralph Lauren black boots and a dark cowgirl hat.
