Antonio Berardi is an exacting designer, and his spring collection stayed firmly on course, though this season he curbed his enthusiasm. A run of organdy dresses — either long and lean or brief encounters — came cleanly constructed, slightly A-line in form, breaking into rounded sleeves or sprouting small ruffles at their hems. Lingerie-inspired bobbin lace insets, a nod to the designer’s Sicilian roots, and scorching shades, namely hot pink, red and turquoise, turned up the heat, as did nods to the season’s transparency themes.
