Honestly, if I hadn't read the Basenotes reviews, I would never have called the note I smell in Parure is plum. It smells fruity, but like you said it has that acidic, varnish-like quality to it. Of course, now I smell it and my mind/nose registers: plum!
Today, wearing it again, I am again amazed at the similarities to Chamade.
I'm still not sure if I like Parure.
