Drawing on the West Coast’s fresh atmosphere and spirit, Louis Vuitton’s ongoing Cologne Perfumes collection conjures up the cool vitality of California. The French fashion house’s Grasse-born master perfumer, Jacques Cavallier Belletrud, created the unisex line and introduced its inaugural fragrances in 2019, including Sun Song, made with lemon to suggest the warmth of the morning rays, and Cactus Garden, a tropical bouquet created by maté and Calabrian bergamot; he unveiled California Dream, a clean, citrusy spritz informed by a sunset, in 2020. (Cavallier Belletrud is also the nose behind Pur Oud, a scent released in April that features an unusually high concentration of oud, a heady essence derived from agarwood trees.)
