Founded by an enterprising milliner in the mid-1800s, this was the one of the world’s first department stores. Despite its name (bon marché means “affordable”), this is the most expensive of Paris’s grand magasins. It is also the most stylish, with beautiful displays and fabulous clothes of every imaginable designer label, both upscale and mid-range. Right next door is their humongous designer supermarket, La Grande Epicerie.
