I own a few modern (around 2005) Mitsoukos - EDT, EDP and extrait.
What can I say about DUA’s Classic - AMAZING! I definitely like it better than the originals in my collection. The reason why is, to my nose, the DUA’s Classic has more pronounced and altogether more beautiful flowery notes, jasmin in particular, especially in the beginning, which changes the mood of the fragrance, makes it more uplifting and joyful, rather then contemplative mood of Mitsouko’s I have owned. A must try for lovers of classic chypres.
