How did London’s most ascendant jeweler end up in an Orange County mall? Rather than following up her American debut on Madison Avenue this past May with a location in Los Angeles or Dallas, Jessica McCormack chose the O.C.—specifically, South Coast Plaza mall, 38 miles south of L.A., and seemingly a world away from her plush New York and London boutiques. LVMH, Chanel, Hermès, and Cartier are all here, too, along with mall regulars Nordstrom, Saks, Macy’s, Bloomingdale’s, an Apple Store, Abercrombie & Fitch, etcetera. New tenants this year include the only West Coast location of Manolo Blahnik, plus Khaite, Skims, Bottega Veneta, Moncler, and Zara Man’s lone U.S. outpost. And Tiffany’s is adding a Blue Box Café—its first outside the New York flagship, Harrods in London, Hong Kong, and Tokyo.
