A few weeks ago, we hopped on a plane to LA to spend a day with 22-year-old artist/illustrator Langley Fox Hemingway for Marc Jacobs Dot X ITG. Though we played dress-up with a trunkful of clothes and accessories from Jacobs' archives, Langley, who's older sister you might already be familiar with (you definitely know her mom and great-grandfather), has a style all her own. She's got delicate line tattoos on her finger and forearm, stacks of vintage rings on both hands (and a thin gold hoop in her nose), and an ever-changing mane. "I started dyeing my hair at seven," she says. "It was bright red and it was orange, it was platinum blond, it was pink, it was blue...I had understanding parents." Her current 'do—cropped onyx bangs and a stick-straight shoulder-length cut—dates back to Halloween. "I was Lydia Deetz [Winona Ryder's goth character] from Beetlejuice, so I got bangs for that, but then I saw The Girl with the Dragon Tattoo and I got a little obsessed. Obviously, I wasn't going to shave off half my head and do weird things, but this is the everyday [version]."
