Which perfumes are mentioned in the movie Scent of a Woman? Are they
still available and from where? (In South Africa if possible) To me
the ones mentioned sounded
something like Ogilvy Sisters (in the tango scene) and something that
meant Flowers from a brook (near the end after the speech, when the
Col. is speaking to one of Charlie's teachers.

In the tango scene, Ogilvie Sisters soap is mentioned.

The "flowers from a brook" is Fleurs de Rocaille.

I'll leave the product search to another Researcher.

Fleur de Rocaille is made by the Perfumerie "Caron" which is a major
perfumerie in Paris. You can likely find a bottle on ebay or do a
general google search for it in your area.
