SHOP TILL YOU DROP: The main escalator at Le Bon Marché Rive Gauche.
Gabriel De La Chapelle

When Le Bon Marché Rive Gauche opened in 1852, it revolutionized retail by selling ready-to-wear fashion and home accessories under one roof at consistent prices that middle-class residents could afford. Engineer Gustave Eiffel (yes, that Eiffel) helped design the department store in the artsy Left Bank district in Paris, and last year, renovations — which included transforming the ground-floor men’s department into an apartment-inspired showplace and adding a barber shop, a shoeshine stand and personalized, by-appointment styling advice — gave a touch of luxury to the culturally significant structure. But the store didn’t stop there. Le Bon Marché also welcomed new in-store men’s boutiques by Dior and Gucci, plus a refreshed ­accessories-and-horology department debuted last month featuring chic watch displays and a tighter focus on trendy timepieces. An experienced watch mechanic is on hand to answer customers’ questions and complete repairs. Next up: a new wine-and-spirits cellar opening in November in the store’s La Grande Épicerie de Paris food pavilion. Black granite floors, sleek glass cases­ and special lighting will protect and showcase thousands of rare bottles from around the world.
