Falconeri, the Italian fashion house, is embarking on an aggressive U.S. expansion, looking to have eight stores operating in the country by yearend. On the heels of opening a 2,000-square-foot store at 764 Madison Avenue in New York on May 1, the cashmere brand will open stores on Michigan Avenue in Chicago in July and Prudential Center in Boston at the end of September. This follows new stores that opened in Short Hills Mall in New Jersey last month, and Westfield’s Valley Fair Mall in Santa Clara, Calif., in February. Falconeri, which specializes in cashmere women’s and men’s apparel, already has stores in SoHo, Flatiron and Hudson Yards in New York.
