I have a very finicky body chemistry when it comes to perfumes and Obsession has been my fragrance for about 20 years. I always get complements on it when I wear it. A little goes a long way, and the fragrance will last all day. I'm not a fan of having my perfume announce my presence before I even enter the room, if you know what I mean, so 2 spritzes is all I need. That means that a bottle will last a long time if you keep it in a cool dark place.
