Obsession by Calvin Klein also boasts an array of other notes that come together to form a fragrance as multifaceted as the woman who wears it. The fresh, citrusy tones of bergamot and mandarin are perfectly balanced with green notes and the creamy warmth of vanillin. Sandalwood and vetiver bring a woody depth to the perfume, while coriander, oakmoss, amber, musk, and incense add an earthy richness that lingers on the skin.
