The Willa: A+O's signature, best-selling blouse body that everyone loves-for good reason. This season’s update is fit for a queen with its aptly printed silk crepe de chine. Finished with a crisp collar, hidden placket, and lightweight feel, it’s polished enough for summer dinners and easygoing enough for daytime strolls. Wear it tucked into denim or open over a slip dress-the kind of top that can do it all.
