You'll be happy to know you can leave your blow dryer tucked away this Fall as the Louis Vuitton  runway was all about carefree, loose waves — even the parts weren't straight! Don't have this cool-girl style naturally? That's why Sarah Potempa created the Beachwaver  (thank goodness). While roots were somewhat sleek, the ends had a slight crimp. If the hair was bedhead chic, then the makeup was high-fashion elegance. There was a bold eye with a heavily pigmented gold shadow on the lids and a darker brown in the crease and around the outer edges. The rest of the face was pretty bare to balance out the party-ready eye.
