Twenty-five years ago, when Ralph Lauren converted Madison Avenue’s magnificent Rhinelander mansion—one of the last remaining turn-of-the-century grand homes in Manhattan—into his New York flagship store, he did much more than set a new standard for luxury retail spaces. Built in 1898, the imposing French Renaissance Revival home serves as a stage on which Lauren can arrange his creations to conjure tableaux of a bygone era when gracious living was very nearly an art form. For years, the rooms of the house, which are adorned with decorative carpets, period furniture, crystal chandeliers, and tastefully appointed accessories, provided an elegant and cordial context for Lauren’s comprehensive men’s, women’s, and home collections. The timelessness of his style—which contrasts sharply with the fleeting trends that define much of the fashion world—has enabled the designer’s brand to maintain its enviable position as a market leader for decades. His classic sensibility, however, also embraces change: In September—?in commemoration of the New York store’s original opening—Lauren plans to redefine his vision for life well lived with his men’s store’s official unveiling.
