While I love Diane in high-octane fashion shoots, I love her equally on the street. Here she is smiling and running errands dressed down in jeans, boots, and bags. But let's dig deeper. Black and white stripes deliver a yummy nautical flavor, a shrunken light denim jacket feels fully familiar, a touch of icy lavender feminizes, and Balmain's black studded boots still make me swoon. A heather gray headband and A.P.C.'s Beads Bag ($210) are cool, casual touches.
