This fragrance, like virtually every other Chanel fragrance, is a complex, mature scent which is like no other.
The name suggests this is a flanker to the original Coco. However, apart from a few faint traces of Coco, Coco Noir is actually quite different. Despite the 'Noir' in its name, I find this scent to be a lot sweeter than the original Coco. There is a strong orange essence type note in this perfume that lends it this quality.
I love the original Coco, its one of my favourites. The Coco Noir just didn't do it for me, its quite different from the Coco, and I cant say that I liked it very much really.
