There are no rules, really, for masculine or feminine scents. On this board, we have people who gender-bend all the time. I am a woman who will wear just about any scent that I fancy, even the more "manly" scents.
IMHO, overall, the more "floral" a scent, the more feminine it is perceived. The spicier, the more masculine. That is only for me, keep in mind. I picked up a sample of Allure Homme for my husband and he asked if it was one of my new perfumes.
I say wear what you like and forget the label or the bottle! P.S. I am not a "younger" gal, but a gal all the same. LOL!
