I also have very dry skin. I've found Vetiver pour elle's longevity ok, but not on par with other (long lasting) vetivers like Sycomore or Vetiver Extraordinaire. I keep going back and forth on this - sometimes I love it, sometimes it feels a touch too bare and synth, and with just a touch of marine showing through (I strongly dislike marine).
I understand that the superexpensive Muguet appears only once a year, and every year is reformulated, so I guess it depends on the year. I've never had the opportunity to smell any of them. Turin's statement that it is not possible to do a good muguet anymore has so far been confirmed by my experience too, so I'm a little skeptical towards supposed muguets. But, as said, I've never tried the Guerlains.
I don't care much for Jardin de Bagatelles. As for femininity, the gorgeously slutty Nahema might feel feminine to non-perfume lovers. But who cares?
