Lass I wear Grey Vetiver often and I am a boring heterosexual mother of two. Vetiver is one of my favorite ingredients, a great raw material. You are allowed to wear it just like you are allowed to wear trousers, jeans, a smoking jacket or brogues
I read somewhere that 30% of perfumes labeled as aftershaves are actually used and worn by women. There are many great vetivers: Tom's Grey Vetiver, Sycomore by Chanel and, Encre Noire (the masculine version) by Lalique for example. The last one has perhaps the most beautiful bottle I own.
"Male" perfumes were created to lure American men straight males in. Men who have more culture and background in perfume-wearing have much more varied tastes. I once sat next to a very masculine bearded Middle Eastern man on the tram and he radiated classy, seductive waves of rose and jasmine. So sexy...
For all women who want to explore the masculine side, great and easy-to-wear men's classics are Habit Rouge by Guerlain (most of my women friends have fallen in love with it - such a classy perfume!) and Eau Sauvage by Dior (ditto - a must if you love radiant citrus). Here in Italy, more and more perfume departments are becoming unisex - you get to choose what to wear without antiquated gender boundaries. Many men I know are crazy about jasmine and iris. And if you like violets, try the original Fahrenheit by Dior.
For me, the most difficult male perfume type to wear is classic fougeres - I associate them with my father. That said, I have a bottle of 1725 Casanova and wear it quite often - the heart is one of the most delicious things ever. One of the greatest fougeres I know is Azzaro pour Homme (may need some of it for winter).
And a random totally unrelated mention - does anyone wear Douce Amere by Serge Lutens? A masterpiece.
