So, here it is. I took these pictures in the library and at least one person was looking at me like I was crazy. Apparently this has a dupe in Orly...Space Cadet? I think. I haven't bought an Orly in quite a while, so I don't have that one to compare. Most of the time Mean and Green looks sort of purply-pink, but if you get it at the right angle there's a pretty awesome rainbow effect. Don't let how cool this one looks fool you, though. Application was troublesome. First, my brush was totally wonky. Bristles sticking out every which way. Second, the formula was thick and difficult to work with. And I needed three coats. And it took forever to dry. Despite this, though, I still think it was worth it.
I'm pretty sure all these MAC polishes are sold out (this one was given to me by the unfailingly generous Michelle), but as I said, this one has a dupe in Orly Space Cadet, which I assume is more readily available.
In conclusion, I'm in love with this polish.
