Today, Valentine’s Day, Prada launched an app for the re-release of its Rossetto parfum (that’s parfum, not eau de parfum—merci very much). Developed in collaboration with the label’s go-to graphic guru Michael Rock of the firm 2×4, the platform lets users pile up random images—ranging from classical statuary to emoji-looking animal faces—in a kind of Duchampian mood board, topped off with that most Daliesque of symbols, red lips. If anyone can create an art app based on a fragrance, but without a hint of the scent or whiff of irony, it’s Prada.
