Ciel de Gum is too complex for a statement, but too quickly explained for a long comment. What else can I do but insert meaningless filler sentences like this one ;).
I absolutely agree with MissKitty's statement. I know that the name here does not refer to rubber, but in the top and heart notes, there is for me a very clear rubber, vinyl, or latex note, whichever you prefer. This may sound difficult to wear, but it makes Ciel de Gum a very beautiful fragrance for me, as it does not come across as too sweet, too tame, or generic. It is merely a contrast, as from the very beginning, this authentic rubber note is embedded in a delicate vanilla-amber fragrance. In the initial phase, the rubber note dominates, but the base notes easily reclaim dominance after a while. In the end, what remains is a velvety-soft vanilla scent with a slight cinnamon note and a subtle, buttery-soft amber. It is truly more vanilla than a typical amber, although Ciel de Gum clearly becomes ambery. The amber feels far too clean and clear to do justice to what is typically considered amber. In the base, there is really only a hint of this rubber note left; a very light, background suggestion; which fits in wonderfully.
I don't know where the impression of rubber comes from, as I don't smell any pepper or jasmine here as I know them. But it doesn't matter - Ciel de Gum is a great, cozy fragrance that I can really imagine on both men and women without exception. Despite its warm scent notes, good longevity, and sufficient sillage, it does not feel overwhelming but rather relatively transparent. I find it somehow sexy. Highly recommended for testing.
While amber scents are often too sweet and boring for me, the gum makes it really interesting :-)
