I find this launch interesting. As avant-garde and undefinable as The Big 5 was when it was created, the last decades of Chanel olfactory adventure have been less controversial and well, sophisticated but uncomplicated. Noirness stands for something else. For me this step brings some edge to Chanel that is in line with using Alice Dellal as muse. I like this step. But then I am generally into the noir.
The internet is swimming in an ocean of reviews of Coco Noir so I will let you do your own googling. What I do have to offer however in terms of treasures is 1) a beautiful article on the noir from Perfume Shrine that dances with this topic in a elegant, ambitious and exiting way. You will find this excellent piece here. And 2) the magic world of Clarimonde created by magic Lucy Raubertas... get enchanted here.
