Editions de Parfums Frédéric Malle is based on a simple concept: take the nine most famous noses in France and have them edit singular perfumes. The result? Exceptional, highly concentrated fragrances to be had nowhere else. Le Parfum de Thérèse, for example, was created by famous Dior nose Edmond Roudnitska for his wife. Monsieur Malle has devised high-tech ways to keep each smelling session unadulterated. At the rue de Grenelle store, individual scents are released within glass columns; stick your head in and sniff (rather Star Trek but effective). The boulevard Victor Hugo boutique has a glass-fronted "wall of scents;" at the push a button a selected fragrance mists the air. Métro: Rue du Bac. Other location: 140 bd.
