A cap can be so much more than something you wear on your head. It is your chance to look cool and develop some swag. They can keep your head warm, add to your fashion sense, and allow you to be more of a hipster. There are all sorts of different colors and materials for a cap, so you can decide which one is right for you based on what you like and the season. Men and women alike can wear a cap, and many a girl will even borrow from the menswear department to look cute. Tumblr has plenty of ideas on personalizing caps, too.
