New York Fashion Week goes by in a New York minute, so who has time for long beauty routines in front of a mirror? Touching up in the backseat of a cab between shows and parties is more like it. Just ask Lisa Salzer, the designer behind obsession-worthy jewelry line Lulu Frost. Since the label's launch in 2004, this blonde beauty has hit style superstardom with her stand-out vintage-modern aesthetic—think Gen Art awards, celebrity fans (Olivia Palermo and Meryl Streep, to name just a few), and an expanding collaboration with J.Crew. We were lucky enough to shuttle this tastemaker around in-between appointments, where she shared tips for freshening up, lickety-split. Her car-friendly Smashbox faves keep her looking glam 24/7.
