One of my favorite houses at the moment. I own and love a handful of their scents. If I had to choose, my absolute favorite 3 are:
Cuir d'Iris: Animalic/Leathery Iris-Amber
L'Ombre Fauve: Animalic Amber (smoky vanilla base)
Felanilla: Animalic Vanilla (with saffron and iris too)
I'd say that the (slight) quirkiness, quality, and simplicity of PG scents make them very very appealing to me.
