"Your first stop should be Sephora at 70-72 avenue des Champs-Elysées – it’s a scentual and extravagant perfumery. Next door is Guerlain’s boutique. Walk through the shop and up the stairs to the first floor. There you’ll discover La Maison Guerlain, and a collection of Guerlain perfumes available nowhere else. The staff could not be more helpful.

Cross the road and walk down rue de Marignan to the intersection of avenue Montaigne and rue François. Visit the Caron boutique, filled with some of the greatest of French classics. And don’t forget to take the time to visit Dior’s boutique next door."
