This is a fragrance I've been curious to try for a while. Unfortunately, never having tried it, I'm not quite sure what to suggest.
No. 88 - if you haven't tried this one yet, do. It has geranium, patchouli, and rose, and it's quite deep and rich to my nose.
Gandhara - jasmine, patchouli, musk, castoreum. Floral but also very dark and animalic.
Soir de Lune - very complex, old-school chypre, with rose, patchouli, vetiver, and moss all very present.
