Kristin Cavallari's punchy-colored top makes her knotted style all the more playful — and perfect for Summer. Just pair your bright button-down with a pair of looser shorts, like Kristin's, and knot at the waist. To finish, add a few neutral accessories, and you've got a great look for brunch or afternoon cocktails.
