Today is the funky unofficial holiday known as Button Day, when buttons, buttons, and even more buttons of every size, shape, and color abound. Buttons are meant for so much more than jeans and dress shirts. They can be part of jewelry, accessories, winter wear, and more. With such a vast array of fashion and function duties, the button is literally everywhere, and on almost everything. And now, one more place is being slowly taken over: your ears. Plugs and tunnels lend themselves perfectly to the round, but never boring, style icon. Just pick your favorite color, pop ’em in, and your look of the hour is all sewn up.
