One of my favorite super dramatic vampy nail polishes is OPI Midnight In Moscow. This is another one from the Russian Collection that came out in Fall 2007. It's a deep charcoal with red shimmer. In low lighting it's velvety and almost black, but in the sun it has this glowing, smoldering look.
The formula is great, it's neither thick nor runny. I needed just two coats for opacity. These pictures are without topcoat, and you can see even on its own the polish is quite glossy.
