Lately, a lot of celebrities have been wearing hats. Hats are the perfect accessory for fall; when you live in a warm climate, it keeps the sun out of your face, and when you live in a colder climate, it keeps your hair nice in case of wind. Plus, they make you look very cool. Hats were seen at the runway shows of Jean-Carles de Castelbajac, Ann Demeulemeester and Blumarine.
