If you’re looking for something to humor her girlish side, try a whimsical accessory, like a sparkly hair ornament that doubles as a brooch. Ban.do—a favorite of celebrities like Taylor Swift and Zooey Deschanel—always offers a colorful selection of headwear like crystal bobby pins, head wraps, and, my current favorite, this Metallic Pom Pom Flower in gold. $15; shopbando.com
