Seriously though, there is no "concrete" answer for all girls ( I guess most teenagers are influenced by what's the latest fad or what everybody wears, but not ladies over that age) and if you're asking about your own girl, why not take her to a sniffing expedition and ask her? You might discover something that way.
Plus an individual perfume will make you stand out more.
Myself I like Declaration, Obsession, Trussardi original, Lolita au masculin, Timbuktu, Mechant Loup, Allure Homme, Egoiste.
And butch, macho ones like Givenchy Gentleman and Cartier Santos.
