NEW YORK — There’s nothing like a seaside inspiration to create an upbeat collection — especially in the right hands. And this season, Anna Sui fit the bill. Over the summer, the designer went to Capri and Positano, and she returned with a passion for surf and beachwear. Sui filled her spring line with shorts, minis, jams and bold floral patterns, and the results were young, fresh and charming. Here, her blue cotton dress with swimsuit details and a scuba mesh T. Cowabunga!
