Noir is our impression of Calvin Klein CK One.What CK One smells likeLemon, bergamot and mandarin open it, with pineapple and papaya adding a soft fruitiness and cardamom keeping it dry. Lily of the valley, jasmine, violet and freesia sit in the middle with a little nutmeg. Green tea, musk, oakmoss and amber close it clean.When to wear NoirAnytime, on anyone. CK One was built to be unisex and it still is. Hot weather, class, travel, days you want to smell like nothing in particular in the best way.
