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. 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. Perfumer(s): David Seth Moltz Notes: bergamot essence, iso e super, vetiver acetate, civettone, firsantol, ambrox super
