I received Chanel Rose Confidentiel as a thoughtful birthday gift from a friend this year. I believe this color was originally released in Fall 2010 along with Rouge Fatal and Rose Insolent, and is still available on the Chanel website. This polish has a very nice formula and is quite shiny on its own. It's easy to apply and only requires two coats.
I've heard that OPI Kreme de la Kremlin is a close match, but unfortunately I don't have both of them to compare. A very demure color, to be sure. It's potentially "boring" in comparison to other colors, but I think it looks nice and elegant. Sometimes this is just the sort of understated color I want.
