I went on vacation to Italy the last two weeks and visited -among many other beautiful cities- Capri (home of Carthusia) and Firenze (home of Lorenzo Villoresi). I noticed that the first one appeared in many niche stores throughout Italy although it's certainly less well known than the latter. Maybe you could try one of their scents (Numero Uno or Uomo are their masculin perfumes) if you can get a hold of it.
In Milano, I asked a shop assistant if they had a special/rare and typically Italian perfume. She returned with... Aqua Di Gio [smiley=embarassed.gif]
