Serge Mouille was a French designer who is best known for his lighting. You may have seen his arm chandelier or sconces floating around design magazines and blogs for many years now.
Original Serge Mouille lights cost in the thousands of dollars, but as many iconic designs, there are plenty of reproductions online and in stores that cost a few hundred dollars. And you can see from the images below that Serge Mouille lighting looks great in a variety of interiors.
