For his debut fragrance, B. Balenciaga, master minimalist Alexander Wang “creative-directed” the process much more than most designers would, bringing his stripped-down-with-a-twist ethos to the juice, recalls perfumer/collaborator Domitille Bertier. “It’s a short formula, with few ingredients. Each one has a part to play; there’s nothing superfluous,” Bertier says of the atypical green woody scent, free of flowery frills. With the lofty ambition to invent a new genre, Wang took two years to fine-tune the notes: green tea, violet green leaf accord, edamame, cedarwood and cashmeran wood. The crackle-textured, architectural bottle—an homage to the marble tile in Cristóbal Balenciaga’s 1936 Parisian salon—is a hat tip to heritage, but also to Wang’s own sharp-edged style.
