A tour of the Guerlain flagship on the Champs Elysées in Paris, guided by Sylvaine Delacourte, Guerlain's Creative Director. In French, but even if you don't understand a word, worth watching if you've never seen the interior.
Guerlain updated their flagship boutique in 2005 with a new design by Andrée Putman (interior designer) and Maxime d'Angeac (architect). You can read more about the renovations of the Guerlain store here.
