The center of Paris couture lies in the Champs-Elys es Quarter with the houses of Yves Saint Laurent, Guy Laroche, Nina Ricci, Givenchy, Christian Dior, Herm s and Chanel. Bringing home French food is grand but make sure it is allowed. Dress appropriately for shopping. Shipping charges can be high and some stores have a minimum. In tourists areas you will find some Sunday openings.
Most department stores use a ticket system so plan on more time to shop.
