You've heard of the little black dress, and it's high time you supplied your closet with a new classic: the little white dress. White is perfect for any season and any occasion (except a wedding, unless you're the bride!). It works for warm weather because it's light, airy, and innocent. White also makes a great canvas for trying out new trends, like a pair of lemon-lime pumps, a statement necklace, or glittering sequined belt. So what are you waiting for?
