Which Calvin Klein fragrance was the first unisex?

Calvin Klein’s first widely successful unisex fragrance was CK One.

Launched in 1994, CK One was created by perfumers Alberto Morillas and Harry Fremont. Its citrus-forward composition includes notes such as pineapple, mandarin, papaya, bergamot, cardamom and lemon, balanced with floral and woody elements. The clean, light profile was designed to be shared rather than assigned to a men’s or women’s fragrance category.

The word “first” needs a little context. CK One was not literally the first unisex fragrance ever made; earlier scents had crossed gender lines. It is better described as the first Calvin Klein fragrance openly marketed for both men and women, and one of the first unisex fragrances to achieve broad popularity in the United States.

Its minimalist bottle and inclusive advertising matched the relaxed, androgynous style associated with the 1990s. CK One became a major commercial success and helped make unisex fragrance a mainstream idea.
