I kept sniffing and liked it more and more and it eventually mellowed into a sweetish vintage powder. Truly a fitting name; 'Blue Hour', the scent of the sky, that is the only way I can describe this fragrance. It is like an entanglement with a forbidden lover: cherished moments that will only give way to memories of blue starry nights caressing under a great big sky.

Iris, violet and heliotrope are the central notes and make the scent powdery, romantic, and yes, a bit melancholic. to me LB is more interesting than Chanel No 5 and I never thought anything would beat that same scent, but wow this fragrance is so impressive and such a work of art. All of that said, if I had to choose from all of the above for a Most Memorable, Evocative, Emotional scent? A bit of that rubber in the old Guerlains which I happen to love, but it has a totally different feeling than those. I love Shalimar, my moms main signature (just got an edt, still so so delicious), so I expected this to be a love love love.I appreciate L'Heure Bleue for its role in perfume history but I feel like a kid playing dress-up when I wear this. Here, instead of the ambiance of opulence of the inner rooms of a palace or the deep, sensual majesty of an old temple, full of woods and incense, I feel the warm hug of a morning (for some reason to me this smells like an early spring or late winter morning, not evening) spent in a boudoir taking some time to pamper myself. I go through periods I like it a lot - then it gets too much and I pack it away for a long time - until it comes around again. When I smell this fragrance, I imagine the moment just between being awake and falling asleep, when the heaviness of sleep is about to pull me under into the limitless blue oblivion.

Guerlain is known for blending in their fragrances with the most lush iris notes and this is top notch. I wouldn't say that this smells old, necessarily, or synthetic, but for many, the olfactory associations are going to be off-putting. After the initial aggressive blast, the vampy middle notes started to come out and she started to show herself. Not even five minutes later, the scent started developing into something else; something soft and old-fashioned, but in a nice way. I also get the coty airspun vibe from it as others have mentioned, but more complex of course and sweeter.Deep, intense, powdery, floral and spicy at the same time, it somehow manages to not get heavy and dense. However, it seems pretty clear to me that many perfumes and other scented products that followed have adopted a similar note profile.
