This is an old thread, but unanswered so, I'll comment. Keiko Mecheri's Musc is an unusual animal with notes of sandalwood, golden amber, tonka bean, crystal musk. It is not similar to the Jovan White Musk, Body Shop White Musk or SL Clair de Musc. It lacks any soft powdery notes or sweetness and balances right on the edge between clean and dirty. I blind bought this because I love Peau de Peche and Loukhoum and the new bottle design, however, I find I rarely reach for this and it makes me feel uncomfortable and unwashed when I wear it. It is almost heading into the realm of the Narcisco Rodriguez Musks, but with much less sillage, minus the figgy or osmanthus and floral top notes and much more transparency. This is for the person who lacks any natural body odor, because to my nose it basically smells like a slightly sweaty muskiness with a touch of golden amber and sandalwood essential oils rather than a structured fragrance. This is a nice base layer to create a sultry signature if you want to wear a super clean, fruity or white floral over it. On the plus side, I find it totally androgynous and could work for some day and night. In my case, I keep trying to layer this with other things, it just feels incomplete somehow. In retrospect, if I had to choose a perfect clean musk, I'd go for Le Labo Musc 25 or SL Clair De Musc with it's comforting iris powder finish instead.
