I'll make a list of feminine marketed Guerlain scents for you fellas to try, in order from unisex to "tough for a man to pull off well:"
Totally Unisex (IMHO):
Cologne du 68
Vol de Nuit
Vega (though $$$ and hard to find)
Samsara (especially vintage juice or parfum concentration)
Tough-ish, but still possible:
Jardins de Bagatelle
NOTE: I'm ignoring Lui, Sous le vent, and Djedi because they are far too $$$ and hard to find. If you ever find them... don't even DARE sniff. Just PM me at once and quote a price.
