Venetia Studium

Inspired by Mariano Fortuny's style (he's the legendary turn-of-the-century designer; they hold the patent on his art nouveau lamps), this wonderful store has clothing, shawls, purses, and accessories, turned out primarily in pleated silks. Pricey, but the quality is undeniable. The main showroom is on Dorsoduro, near the Salute church, though there's another in San Marco.
