NYC cool girl Chelsea Leyland seriously upped her hair game yesterday by going for some triple threat plait action at a party in New York hosted by Gucci and Vogue. Plaits are everywhere right now: celebs like Cara Delevingne have been spotted sporting a mini version, ASOS German editor Lia Haubner created her own how-to guide, the Marc by Marc Jacobs recent catwalk show was all about a good-girl-gone-bad punky version and Simone Rocha's models kept theirs messy at last week's show. For Chelsea's urban-warrior vibes, separate your hair into three sections and do a French braid on each. Thanks Chelsea! 

See how celebrities like Jourdan Dunn and Chanel Iman are doing plaits.
