We've always adored chic summer dresses, and Emma Watson is clearly on the same page as us. Her preppy blue linen dress with black buttons sings cute, casual, summertime fun, just in time for the opening of the Harry Potter theme park. Summer dresses make traveling easy, but are also perfect for going from work to nighttime adventures. The light blue and jean styles feel like the overalls we used to wear on the playground. Now that you're craving a carefree summer dress just as much as we are, pick your favorite style.
