Spring has sprung, and with the warmer weather comes a new wardrobe. Maxi skirts, sundresses and ruffle tops may come to mind, but color is just as important. While zesty yellow and petal pink are crowd pleasers, Sharon Stone and Meryl Streep are turning our attention to this season's hottest hue: blue. Stone wore a soft, airy version of the color, coordinating her blue sweater with a trench coat and loafers. Meanwhile, Streep nodded to her on-screen persona, Miranda Priestly, by reaching for a cerulean blue J.Crew cable-knit sweater.
