I had Eau de Nuit I think before I owned Dior Homme, La Nuit de L'Homme, Herod, The One, and many others. It was actually one of my first good, - to better fragrances.
I can still remember how I enjoyed and celebrated that sweet-spicy vibe back then, it really made me feel special when wearing it, as I had never consciously smelled anything like it on anyone else. (Powdery-sweet-spicy men's fragrances...)
However, has the fragrance for me something about it, which leads to the fact that I have worn him over the years then hardly.
I quickly came to the forerunners of the genre (Dior Homme series, for example), which for me are simply even more interesting and tingling to smell, and to wear.
And from that point on, this fragrance was just too redundant.
Which is actually odd... let's look at the notes:
Bergamot, cardamom, cedar.
A tried and true blend from La Nuit de L'Homme, my all-time favorite scent.
Iris, amber, tonka bean, heliotrope.
Iris (Dior Homme), Amber (e.g. Baldessarini Ambre, or Prada L'Eau Ambreé), all very sensual notes or accents, which I also like to smell.
But hello... so much sweet at once, that's almost overkill. Honestly, half of it would certainly be enough.
But why not design a more complex fragrance, than him only (as so often Usus) build on tonka bean or so...?
But I'm afraid that's exactly what Eau de Nuit does wrong: too much of everything.
Now after years(decades)of using DH, LNDL and companions, I smell Eau de Nuit, and can switch in my head: I can either feel it in its lush entirety, or perceive the olfactory axes in isolation, thinking of fragrances that have a similar set piece.
For example, sweet, powdery iris from Dior Homme.
But somehow there's always something too much, it's too full and overflowing with sweet-spicy accents, making you feel "overdressed" with it all the time, I think.
It's like putting a cocktail cherry, a dollop of whipped cream, and then sprinkles of sugar on top of Dior Homme Intense. This is just too much of a good thing!
Thus, the fragrance is for me somehow hardly suitable for everyday use, and also in the evening or on occasions, there are then just too many alternatives in this direction, which have a better counterbalance, or are simply better balanced.
Eau de Nuit is probably simply also a different target group (as I Jungspund ;P), it is rather for the 45+ year old business gentleman intended, who does not want to seem too plump at the dinner party, by wearing for example Armani Code.
Just a bit more special, but at the same time not too flashy, and yes not too much tarnish.
By the way, I actually feel Eau de Nuit like a more grown-up, perfumier version of the Code series, which also tends to be too sweet for me. But just clearly the Armani DNA.
Finally, I would like to say, somehow I still find the fragrance special, and very well done. However, he is by described problems never quite ascended to my fragrance Olympus.
Who but Code, or other very sweet things like to wear, could find something special here that something more dignified and adult works, and still powdery, sweet and spicy underlines the masculinity.
