Calvin Klein first tested the fragrance world's waters, releasing Calvin Klein perfume for her and Calvin Klein cologne for men. Soon to follow was his unisex perfume CK One, the first of many popular CK scents. The line of Calvin Klein fragrances has since expanded to encompass cologne and skincare in addition to perfume.
Calvin Klein perfumes are known for allure, boldness, and spice. Signature scents include Eternity, a sweet Calvin Klein perfume for her, and the oriental Calvin Klein cologne for men's Obsession.
