Les Lunes (leslunes.com), a sustainable French fashion house, will open a store at the Shops at North Bridge (500 N. Michigan Ave., Lvl. 2) on March 30. The brand describes itself as “addicted to soft,” and its fabrics are sourced from bamboo. The Chicago store will mark Les Lunes’s fifth brick-and-mortar location, and its largest shop to date. Les Lunes’s collections include women’s ready-to-wear, men’s underwear, loungewear, active clothing, and more. In short, there’s a whole lot of softness coming to Michigan Avenue.
