So many reviews to do, so little time. It's tragic that I've only just gotten around to pen my thoughts about this stuff. I don't know whether I'm just having a Eau de cologne renaissance but I really am in love with this kind of fragrance at the moment and it's not even the weather for it. Maybe that's the beauty of this sort of classic perfume...it's versatile and timeless. In any case my respect for Guerlain couldn't be higher and this really is a gem, despite the obvious comparisons with a million other similar fragrances. The opening is like a cool breeze of luscious, bright citruses and lemon verbena which often gives a little fizz to proceedings and although in broad terms, not a long lived perfume, the citrus does last throughout. This might be due to how Cologne Imperiale, superbly transitions into white florals but they are very light and delicate. The drydown has a hint of creaminess like a woody vanilla but so subtle and barely registering as such. It's brilliant! I really like it. This type of perfume can be quite boring but this has something about it an air of class and robust heritage. I have tried it through the years and this latest formula doesn't seem to have lost anything. I didn't expect decent performance and as such was pleasantly surprised when the longevity was okay, low lying but perfectly acceptable.
