Long associated with the supermodels of the 1990s—Cindy Crawford, Naomi Campbell, Kate Moss and Christy Turlington—skinny eyebrows are making a strong comeback and are now reshaping cultural norms. Spurred by Bella Hadid, Gabbriette Bechtel and Nicola Peltz Beckham, their aesthetic is evolving. Social media no longer associates them solely with the ’90s, but with the golden age of Tumblr, when the mood boards of Lana Del Rey, Sky Ferreira, Alexa Chung and the heroines of Skins dictated the codes of a deliberately imperfect beauty. Gone are the soap brows and ultra-thick arches: make way for thinner, slightly arched, heavily plucked eyebrows that evoke flash-lit selfies, smoky eyeliners and the indie sleaze looks that defined an entire generation.
