Miller was snapped all prepped to board her flight from LAX in gray sweatpants, a worn-in striped top, and sneaks. But here's where she stands apart from the rest—she gave the comfy combo an elevated high-fashion spin with the checked monogrammed Burberry Prorsum blanket poncho (a coveted piece ever since it first debuted on the fall/winter 2014 runway) draped casually over her shoulders. In her grip, she clutched a black carryall and a cozy shearling topper—perfect for chilly cabin temps.
Thus far, we've only seen the blanket poncho as street-chic outerwear (proof: Olivia Palermo, Sarah Jessica Parker, and Rosie Huntington-Whiteley), but as an airplane essential? Umm, genius! Follow in Miller's footsteps and treat yours ($1,395; burberry.com) as both a blanket and a poncho on your next flight.
