Covering your head when the weather gets chilly is not only practical, but also stylish. So try donning a chapeau this fall for a different look that keeps your head warm. They're perfect for those bad hair days! Here are a few trends to try. Consider your personal style as you choose a hat style - do you favor a boho look? Romantic? Inspired by menswear? Or are you just interested in keeping your noggin and ears warm? Regardless, there's a style out there for everyone. If you like a casual, boho look - think flared jeans, wedges and tissue tees - give a floppy, wide-brim hat a try. And we're not talking about that straw hat you sport at the beach. Cozy fabrics like flannel will keep your head warm. Rachel Zoe, Blake Lively and Rihanna have all been seen sporting floppy hats with jeans or maxidresses. Don't feel like going big?
