Mom used to say that most of your body's heat escapes through your head. And although technically, this isn't true, any surface left uncovered in frigid temperatures is not a good idea! And if your next excuse is "it will mess up my hair," quit your whining because I've test-driven a few styles that will up your fashion ante and keep your hair coiffed. The key is to pick something with some structure, that also covers your ears. I'm a big believer that headbands do not fulfill the same warmth prophecy. My favorite style this season is something similar to the Modern Girl Slouchy Cap from etsy's Raimbo Tree. Cozy and comfortable! I also love the more 1920's inspired look of BoringSidney's Barbed Wire Cross Cloche, for a more vintage girl-about-town look. Check out my SLIDESHOW for hat options that won't make your hair-do a hair don't!
