Cara Delevingne's Black Ribbon Headband, 2017 Inspired by "London punk rock" for the UK premiere of Valerian and the City of a Thousand Planets, hairstylist Mara Roszak tied a black ribbon around Delevingne's icy blond pixie cut, cutting short, side-sweeping fringe and long, face-framing layers that she pulled in front of both the band and her ears to soften the overall silhouette of the style.
