With delicate features, pillowy lips, silky blond locks and zero trace of stubble, 18-year-old model Andrej Pejic’s androgynous looks have graced a slew of runways including those of John Galliano, Raf Simons, Paul Smith and Jean Paul Gaultier, who dressed him as a Betty Catroux look- alike in itsy-bitsy briefs. “I may as well push it to the limits,” he said backstage at Paul Smith on Sunday. “I wouldn’t dress this way if I didn’t have fun with it.”
