Well, last review for at least a couple weeks.
Unlike most of my previous reviews, this is less than on-the-spot as I've tried this a couple times before.
First of all, this perfume has the most glorious top note I've yet smelled; rich, sweet, dew-covered tuberose flower. Nothing artificial about it; it's as good as holding the real thing. Then things settle down a bit, and green scent gets mingled with a slightly different tuberose note mingled with muguet; cool "white florals". As lovely as it is, it can't help but feel a little pale compared to the incredible top note. This blend, rather like some of the other Frederic Malles I've tried seemed to fade rather than develop after the initial burst. There's no sense of previously unknown base notes emerging, but on the good side, there's no nasty surprises either. Like walking away from a garden, it just slowly disappears.
Very beautiful, very direct; not as unbelievably fantastic as the top note suggests, but even without that note this would be a first class perfume.

First of all, bear in mind I've never smelled acacia, so I'm hampered in my review here. There is one strong floral note that dominates the blend, with others in the background. I get a bit of citrus - perhaps orange - and a bit of orange flower. Most important to my nose is a weird murky note that's buried under the others: I can only describe it as smog, and it rather ruins the naturalness of the scent for me. Otherwise, a fairly unremarkable floral with a few vanilla-ish base notes later on.

Okay, I'm not giving an entirely fair review of this perfume, as I put it on a few hours ago and now I have to wash it off ( because I need a bath, not because of any dislike ).
This is the driest of the perfumes I've tried so far: only Creed's Cuir De Russie comes close. It is also very different in other ways; where as the spice in the other ones I've tried is married to sweet incense, this is strongly herbal. I smelled pepper and something like tea tree, mixed with a bunch of intense, Mediterranean-type herbs. Really invigorating; the "butchest" fragrance I've smelled so far. After a while a kind of fresh vegetable scent appears, a little like cucumber.
Right now the vegetables and herbs are turning into a conifer forest scent, but unfortunately I won't get see where it's going.
As for the name... ouch. The name in the States is supposedly going to translate as "Thunderwood". Oh well, at least they didn't call it Schlongimar.

I have a bottle of orange-flower water; it's a very beautiful scent, very evocative of dew covered flowers. Take that scent, replace the orange-flower with lilac, triple the strength of the "dew" component of the scent, and you'll have a very good idea of what En Passant smells like. It's quite mild, and by far the softest of the perfumes I've smelled so far: if it was a picture it would in pastels, not oils.
As it fades, the green notes predominate, with a bit of freshly cut grass thrown in. Its after-scent is slightly disappointing to my nose ; the lush green scent disappears and all that's left is a rather ordinary floral perfume. However, this only appears after six hours, so there's a lot of green to enjoy.
Like Bigarrade Concentree - and unlike the Creeds and Knize - this gradually fades rather than actively develops, but unlike Bigarrade Concentree, the fade is very pleasant and never stale.
To sum up, a nice little fragrance; very mild, very natural; soft and green rather than big and bold. This isn't a scent I'd use every day, but if I was feeling sick and not in the mood for anything heavy and complex, it might be just the thing to cheer me up.

I went for a walk to the Gorge this afternoon, and saw a group of seals! Sometimes the Gorge looks so river-like it becomes easy to forget it's salt water. They were only a few feet away in the water, and weren't at all bothered by my presence; they were too busy eating some form of sea-life on the sides of the gorge. I really hope my camera gets back soon so I can catch moments like these when I'm out walking.
Anyway, on to perfume #3, Bigarrade Concentree.
There's really not a lot to say about it: peel a mandarin and you'll get the full experience. Gradually it fades and looses freshness, and it's mostly gone right now even though I put it on an hour and half ago. Compare that to the tenacious - I had to wash it off - Royal English Leather and the extremely tenacious - I couldn't wash it off - Knize Ten, and it comes across as rather feeble. It's a decent orange scent - it could be fresher - but it's never something I'd buy at the current prices.

Edited to add: A few hours later and there's definitely a whole stale fruit-salad thing going on. Insert "Do Not Want" macro here.
