Cara Delevingne's Sparkly Pixie, 2017 Delevingne used loose glitter as a way to dress up her classic pixie cut, which at the time was too short for most barrettes and hair baubles. The aquamarine-coloured sparkle started along the bottom half of her hair — encircling her ear — and extended right down her neck, creating a seamless stretch of sparkle from head to toe.
