At 63,000 square feet, the new H&M store in New York City’s Herald Square is the fast-fashion retailer’s largest location in the world. The site pits H&M, which has shaken up the retail world in recent years amid very competitive apparel prices, against Macy’s historic Herald Square store. Both locations, and countless other destinations known as 'flagships', are designed to showcase the top-tier assortments in a given season. And who do they want to showcase the latest threads too? International tourists, that often flock to flagships destinations in major cities for brands they recognize from back at home. As for H&M, the gargantuan new store is one part of its broader push into the U.S., where it will cross the 400 store mark this year. TheStreet’s Brian Sozzi talks with H&M North America President Dan Kulle about the new store, and the retailer’s plans in the year ahead.
