As everyone subscribing to Basenotes knows, Jicky (1889) was the second scent to utilize synthetic notes in its composition. The first was Houbigant's Royal Fougere (1888).
Jicky was a failure with the ladies, too brutal and "new," but a hit with men, who kept it afloat until decades later, the ladies came around.
Mouchoir de Monsieur translates as "Gentleman's Handkerchief" and it is apt, as in 1904, the year of its release, men and ladies still brought scented handkerchiefs to their nose when traversing the foul and fetid streets of Paris. Since Jicky was aimed at women, it makes sense for Guerlain to formally market the same scent to men with a bit more base, civet and patchouli. However, it is pretty much identical to my nose.
The combination of lavender and vanilla has a dry, edgy scent, reminiscent at times of damp cardboard. However, controversial, it is still a rather unique scent, regardless of the name under which it is marketed.
I loved it when I first came upon it four years ago, but soon grew tired of it, registering it as having historical import, but no personal impact.
Turin gives it four stars, calls it a "rich lavender," and notes it befits the image of "Rupert Everett playing Beau Brummell."
In any case, it is every bit as good as Jicky with a bit more depth in the base. Since Guerlain simply copied its own scent intended for women, reshaping it for men, it can't be labelled a rip-off.
It's overall quite good, quite unique, and worth everyone's experiencing it.
