OK, I have lived with the Mure et Musc Extreme for three years now and finally feel like I can review it.
My initial impression was just that it was "safe". Something easy to wear, nobody would notice really, not sexy, just good and pretty smelling, light. Great scent for a kindergarten teacher or for situations where perfume isn't appropriate; it flies under the radar. But it is also, conversely, the perfume that I get the most comments of "sexy" on from men, oddly enough. Consistently.
I really, really do love this smell. It's unspecified berries, citrus, and musk, but the musk is animal enough that the perfume doesn't sit on top like clothing, it sort of sinks in and mixes with my skin, it smells human, not like I am a plant, or fruit, or flower; and the fruity smell doesn't ever get unpleasant or cloying even in deepest summer here.
At times I am really quite irritated by paying so much for what is, really, just an idealized body wash scent, except that it's SO idealized that it's damn near ideal.
A story - a few months after I'd been going out with the Boyfriend (I always wore the Mure et Musc Extreme around him, we hadn't had any perfume conversation and it's my backup smell for those situations) , one day he says, smelling at me: "you always smell so good." So I say "yeah, that's the perfume, the mure et musc." and he replies, "no, I don't think so, it's your shampoo or something, or just the way you smell, your biology, you smell so GOOD." He really didn't believe it was perfume.
That, to me is the genius of the Mure et Musc Extreme. It doesn't smell like perfume, nope. Doesn't develop, doesn't challenge, is not artsy or elegant, it just smells good, like I smell good.
I like this better than the original, the original is more sour and herbal and 'bracing' to my nose, this Extreme version isn't more extreme, it's just lower pitched, the berries are tuned louder but the overall impression is softer, rounder.
