(Model is 5'7" and wearing XS) It isn't hard to see all the reasons we love the Rousseau Floral Brenna Mock Neck Ruffle Blouse, this best-selling silhouette is back! A ruffle edge neckline tops the blouse while shirring takes place below the neckline seam. It has voluminous ruffle layered sleeves and maintains a relaxed fit that can be worn tucked in or out of your favorite high waisted bottoms.
