Paris's Musée d'Orsay, renowned for its collection of Impressionist paintings, is about to become home to a rather different kind of legendary work. From January 6 through 28, the side of the museum will be covered with an enormous Chanel No.5 bottle made entirely from 1,200 hand-assembled sequins. The ad itself is going to be absolutely massive as well, covering 2,890 square feet of the museum, and will be visible from the Seine. It's a rather decadent way of advertising, but would you expect anything less from Karl Lagerfeld?
