The Ariana is a softer, more feminine take on a classic silk blouse, with a split neckline, drapey puffed sleeves, and an easy shape through the body. (There's also a hook-and-eye closure at the top of the neck, which can give it a slightly different look when you wear it closed vs. open.) This one's made of our favorite luxe, weighty-yet-seasonless, 40momme, 4ply crepe de chine.
