CK One by Calvin Klein, Clean, pure and egalitarian in its design, Ck One remains an iconic Calvin Klein scent and a go-to for the edgy urban set. The first majorly successful unisex fragrance, this aromatic chypre blends just enough green notes, succulent fruits and musky essences to create a fragrance that complements him or her. Top notes of crisp bergamot, juicy pineapple and fleshy papaya melt into a floral heart heavy in romantic rose, jasmine and violet. A touch of nutmeg gives way to a base of erotic musk and dewy amber. Introduced in 1994, Ck One is the work of noses Alberto Morillas and Harry Fremont. Fifty-year-old American fashion house Calvin Klein released the fragrance in a cutting-edge marketing campaign complete with gender-ambiguous models and a bold “One for All” slogan. Years later this refreshing citrus aromatic continues to intrigue. This fragrance comes in a simple matte bottle with a twist off cap.
