After 11 seasons in Milan, Calvin Klein Collection’s Italo Zucchelli brought the show home to New York. And it can hardly be a coincidence that the creative director’s first show in Calvin Klein’s hometown stayed truer to the brand’s identity than any of his previous efforts. The show opened with slim gray suits with monochrome furnishings, and continued with variations on the themes of sharp tailoring and mélange fabrics. The West Side Story soundtrack gave a knowing wink to Calvin Klein’s home base in West Midtown. The change of venue is supposedly temporary, but perhaps it shouldn’t be. With Thom Browne and John Varvatos both showing in Europe, Zucchelli suddenly looks like he could dominate the men’s scene in New York.
