Key Notes:- Top note: Bergamot Essence- Middle notes: Iso E Super, Vetiver Acetate- Base notes: Civettone, Firsantol, Ambrox SuperAbout The Fragrance:A fragrance enhancer with transparent radiance that gives any perfume a certain, as the French say, "I don't know what.""I Don't Know What is a wonderful tool for anyone who wants to play around with perfume. Of course it can be worn as a modern wonderfully transparent aroma, but it can also be layered over anything. Often when I leave the house, I will wear a touch of sandalwood, rose, jasmine, patchouli, oud, etc. These oils are lovely but can be muddy and they don't last more than a few hours. Idkw sprayed over them makes the oil into a Perfume. It does this because it is made with no notes!It is a secret combination of materials that perfumers use to highlight and enhance notes in a perfume. A Bergamot accord announces freshness, Vetiver Acetate a thin amber, Firsantol a lingering sandalwood, Iso E Super a radiance, and so on.It is like a building with only structure-no interior. You can fill in the interior with an oil, a scent you like, even an old scent that has lost its way. Idkw is built to layer and enhance everything else it touches."-D.s.
