I have an original Organza Indecence, and a sample of the SL Bois de Vanille.
Let me preface this by saying: my skin dries most things out very severely. These two on me smell absolutely incomparable. OI is a soft, creamy, woody scent which dries to a wonderful sandalwood. BDV smells like burned sugar at first, develops to an "old lady drawer sachet" (for lack of a better way to say it), then becomes a non-descript white musk.
It is funny, too, because I tried the BDV on a recommendation that it might not dry out so much when I wear it! Skin chemistry is everything, it seems.
