ON THE DOUBLE: Stella McCartney is doubling up in Paris. She is to open a 2,000-square-foot location at 231 Rue Saint-Honoré by the end of the year, WWD has learned.

McCartney opened her first boutique in the French capital in 2008 in picturesque Palais Royal, also home to such retail banners as Rick Owens, Acne Studios and Pierre Hardy.

The British designer will land on one of the hottest shopping strips in Paris, which recently welcomed the first French outposts for Alexander McQueen, Coach and Tory Burch.

McCartney’s new boutique is to replace the popular chocolate-maker Jean-Paul Hévin, which is to close its two-level unit, which included a restaurant, on April 2 and relocate to a nearby courtyard.
