What’s a casual, coat-slinging gal to do when the weather calls for buttoning up? Throw that coat/sweater/scarf combo onover your hair. Keeping your tresses tucked in is the outerwear equivalent of bedhead, and winter's answer to beach-babe hair. It’s the uncalculated-calculated charm. Go full faux-bob in a turtleneck, or hint at your hair’s true length with a few face-framers. Tie your scarf around it to save yourself from being wind-slapped, or flaunt your long locks by strapping them into your coat, like they do at Maison Martin Margiela.
