Obsession is a fragrance intended for use by Men by Calvin Klein.
Calvin Klein introduced Obsession in 1986. Several catalogs and websites report something along these lines of the fragrance's scent:
Top fragrance notes: bergamot, lemon and sage.
Middle fragrance notes: fern, carnation and amber.
Base of the fragrance: moss, vanilla and benzoin
However, I myself detect strong notes of cinnamon in the base and anise on top.
I love this fragrance. As my mother puts it, "it doesn't smell like many other men's perfumes—like pine needles and gin and tonic." I could not agree more.
My girlfriend, on the other hand, dislikes the fragrance because it is so very pronounced and, "spicy."
