Many fragrances behave like this. Some only really come into their own when it's warm, while others in fact can only be worn in winter.
I had similar experiences like yours with Divine L'homme de Coeur, GdC's 8 88 and very recently with M. Micallef Black Sea to name a few.
That last one I sampled in summer and fell for it immediately, should have bought it there and then, because when I finally did, about a month ago, it was very cold and it stays very close to the skin. But I don't worry about it all that much, for I know it will be awesome again when the temperature starts to rise.![]()
