Wear a white sweater dress and leggings if you're on the lookout for an outfit idea for when you want to look laid-back and cool. A cool pair of tan uggs is an effective way to bring a dose of casualness to this outfit. During the winter season, when functionality is paramount, it can be easy to settle for a less-than-stylish ensemble in the name of functionality. This ensemble, however, is a striking illustration that you can actually stay snug and remain equally stylish during the winter season.
