Scentemental guessed it - Devin by Aramis!
Okay, the one I am thinking of is a stronger version of its weaker brother. It came out probably in the late-ish 90's. Its brother is not a powerhouse but many regard the one I am thinking of as a definite powerhouse contender. It is no longer available as far as I know, but its weaker brother is.
.. the gorgeous Opium PH EDP ?
I'm thinking easyfish guessed it, but I consider the EDT to be a ph too!
Another clue: We have already talked about a number of other fragrances from this same house.
The original weaker version was released in 1984/5, I am not certain of the stronger version, but it came later. I got a bottle in 1998. American company, very unAmerican name. Ciao
Polo Crest Ralph Loren????
...drum roll..: Escada PH EDP !?
