Obsession set the world on fire with its powerful sensuality. It revolutionized the prestige fragrance business with its feverish intensity and irresistible appeal. Calvin Klein said, I wanted to evoke the sensuality and ardor of an impassioned woman. A woman who allows herself to experience a romantic obsession and invites a man to do the same. When he asked the question, Who hasn't felt passion beyond reason?, he tapped into a special fantasy that any woman could relate to.
