Cuir Beluga opens with a blast of syrupy immortelle, vanilla and a pinch of well behaved patchouli. As it dries down it becomes a super wearable powdery heliotrope and vanilla with tinge of golden amber and a discernable hint of a transformed darker immortelle still lurking in the background. The far dry down is mostly a sheer and slightly salty amber, probably ambroxan. If this were a fabric this would be cashmere, it's far to delicate a scent to call to mind something as durable as leather.
Overall it is pleasant to wear and unchallenging. Those who typically don't like scents that feature leather as a concept should still consider trying this. While it's marketed as a leather the accords don't strike me that way an any stage, calling it suede feels like a stretch too. I'd say it's a very safe blind buy for those who like sweetish, powdered amber skin scents.
