Calvin Klein Obsession Eau de Parfum perfume spray for women has a feverish intensity and an irresistible appeal. Addictive and long lasting, Obsession sets a sexy, provocative mood by day or by night. Green top notes of begamot and mandarin soon reveal the heart of Obsession, composed of exotic spices blended with jasmine and orange blossom. Ambery musk and incense combine for a warm, persistent finish.
