Montale Black Oud all day long.
Etat Libre D'oranger: Rein
But the strongest i have ever encountered so far
was a duplicate of Black Afgano, i believe it was made
of 40% concentration, you would smell it a mile a way.
Had to sell it t o a relative. Can not get my hands on
another one though.
For me personally, fragrances with this description would have to be Dior Poison, Fracas, YSL Opium, and Calvin Klein'sObsession and Safari. Oh yeah! I almost forgot Dior Organza...smells gorgeous, but use in moderation!
