What is Calvin Klein CK One EDT Spray Calvin Klein design house launched CK One in 1994 as a citrus aromatic fragrance for women and men. CK One is a defining aroma in perfume making and breathed new life into citrus and marine fragrances, while reinventing the unisex perfume. Calvin Klein CK One has a clean, honest fragrance with a liberating point of view, a refreshing and intimate combination of glow and sensuality to be shared by everyone. CK One notes consist of pineapple and green notes with mandarin orange, papaya and bergamot followed by cardamom and lemon with nutmeg, violet and orris root. A flower bouquet of jasmine, lily-of-the-valley and rose enriched with sandalwood, amber and musk complete this unique composition with a touch of cedar and oakmoss. This iconic unisex fragrance is recommended for daytime wear.
