Alright, so bad news... this isn't the super duochrome version of Black Tie Optional. Good news? It's still gorgeous. The version I have is a darkened blackish purple with purple shimmer that seems to glow from within the polish. I'm not upset at all that I got the "dud" version because 1) I can see myself wearing this a LOT in the fall/winter and 2) I have almost a full bottle that I got for free! Who could complain?
