This perfumerie 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. 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 in glass columns—just stick your head in and sniff. A second boutique at 40 av. Victor Hugo has a glass-fronted "wall of scents," which mists the air with a selected fragrance at the push of a button.
