Calvin Klein's Obsession was one of the earliest releases in the designer fragrance craze, and it has since become a classic.  Obsession is a warm, earthy, sensual scent.  There is no floral or sweetness to it; rather, it has a musky, almost masculine quality with a bit of a vanilla note.  The scent is gently seductive--alluring enough for romance, but also subtle enough for everyday wear.  In has excellent staying power, as it lingers on the skin all day long.
