From JCrew: "A clean silhouette in feminine silk for a look so chic it's never an understatement (it dresses up or down with equally effortless charm). We couldn't help but hide a contrast interior trim for a secret bit of wit—tucked into trousers or pencil skirts, it's our go-to blouse for polish on top. Back keyhole with covered button closure. Long sleeves. Functional buttons at cuffs. Import. Machine wash."

Available in classic navy, wreath (pictured), and cobblestone. Reviewed by Shopping With M here. Reviewed by NY-C: Clothing, Calories, and City-life here.
