Well, hello. I am a lover of Calvin Klein!
It's one, actually, I have a hard time finding parallels to; I find it unique.
But it has a metallic aspect not unlike Chanel 19, and a quality I can only call 'squeaky' clean, a tart soapy bit like what you might recall from some bigger masculine fougeres: Paco Rabanne had it; so did Pour Monsieur. And ironically, the scent it reminds me of most is also a masculine, Nicolai's New York.
Clearly, it's the sort that would be unisex by today's standards, if not masculine, and it's not sweet, just a tad spicy. I can't think of what else to say! It's really enjoyable.
