Prince, one man, one word!
Don't be embarassed, it happened to me also. The first time I smelled it, I was like "Oh my, that's gorgeous! But....where IS the carnation?"
But I loved it so much I had to acquire a decant immediately and shortly afterwards I upgraded to a full bottle. A truly well-blended, milky, indolic jasmine is the most prominent note on my skin. Now that I think of it, that's the exact same reason why I so love the new Haramens from Pierre Guillaume (an old friend of yours!), although the two are by no means identical.
And you're absolutely right, the main theme lasts forever, so that the fragrance seems to have almost no development.
