I'm a big fragrance connoisseur as I have over 20 bottles in my fragrance cabinet ranging from Nautical, Versace, Lacoste, to my personal favorite, Gucci.  I'm very particular about my scents and was not a big fan of CK as I felt as though they were the JC Penny of fragrances.  However, Obsession has given me pause as I find it's rich and elegant scents to be rather complimenting.  I like to categorize my fragrances into sections such as sport, fresh, executive, etc. and I find Obsession to fall into the executive category as it feels like a mature scent without reeking of "old man" like Old English Leather.
