Talk about the life aquatic. Sofia Sizzi created an undersea fantasy world at Giulietta that showed she can be as playfully kitsch as she can be elegant. Consider the huge sea-creature sunglasses, elongated sequins that resembled fish scales and the seashell embroidery that created a barnaclelike surface on bras, bustiers and collars. Sizzi even refashioned her familiar polka dots into hand-painted shell and fish patterns on a navy jumpsuit and midcalf dress. But not everything was fun and games: Her mermaid dresses in delicately jeweled black and navy silk had a no-nonsense elegance, while the pale, ocean-tone lace coats, bustier dresses and skirts added a charming note to the body-conscious collection.
