STATESIDE BOUND: Roland Mouret has more to celebrate today than his fall runway show in Paris — the designer plans to open his first New York store this summer. Mouret met recently with Swedish architect Bozarth Fornell about his plans for the 1,400-square-foot Upper East Side space. Located at 925 Madison Ave., the designer will take over what used to be the Bang & Olufsen space. This will mark Mouret’s second freestanding store. The New York location will sell the designer’s ready-to-wear, accessories and his White Collection, as well as reissued items from his archives that will be offered in the U.S. for the first time.
