Rue Saint-Honoré– Upscale street and one of the longest, across from the Louvre and Tuileries with designers such as Hermès, Goyard, Louis Vuitton, Celine, and Chanel.
Boulevard Haussmann– Home to several big department stores like Galeries Lafayette and Printemps.
Avenue des Champs-Élysées- Big-name French brands like DIOR, Louis Vuitton, and Guerlain. Also, a massive Sephora is located here. This is honestly, my least favorite street to shop in Paris. There are much better options elsewhere and not as crowded.
Avenue Montaigne– Christian Dior was one of the first designers to open here and soon everyone followed. You can find all the French luxury houses on this street.
La Rue Du Commerce– Located in the 15th, a street filled with local boutiques, and a preference for the locals to shop here
