To accompany its Autumn 2010 exhibition, Diaghilev and the Golden Age of the Ballets Russes, the V&A had perfumer Roja Dove create a scent named after the great theater's founder. So what does Diaghilev smell like? Apparently a rich, old-fashioned chypre with notes of bergamot, rose de mai, oakmoss, and vetiver. What do you think? Would you buy museum fragrance, or is the concept just too strange?
