I have some "secret" scents too, things I enjoy for a variety of reasons.
Priscilla Presley's Roses and More...which I wear when I need a scent I can spray recklessly and need a rose (can't be reckless with Sa Majeste, at least I can't)
Balenciaga's Cialenga: a spicy chypre of a sort
Jacomo's Silences: a very green mossy floral, don't know why anybody would name this "silences"
Weil de Weil: Always loved Weil and this greeny in a summer fave, but far less known than Zibeline or Antilope
and while I'm on a green tangent, AL Moss, is rarely among the Serena scents I read about here, but never ever fails to attract loads of admiration from women, never men.
Oh, and Senso by Ungaro, I'm the only one I know who likes it.
