Black Phantom (“Memento Mori”), the latest fragrance from By Kilian, is a fragrance that is a far cry from the terms and imagery surrounding it. The phrase “Memento Mori” means “remember you must die” in Latin, and was given to objects which were meant to make you ponder or remember your mortality, like skulls. And, indeed, a glittering black skull is placed right on top of Black Phantom’s perfume box.
