Here's the mani I did last week using OPI Merry Midnight. It's from the Holiday 2009 collection and thanks to Mistress Zombie I was able to get my hands on it for a reasonable price. It's a purple base with pink/red flakies and purple glitter. I also got Holiday Glow which I love. Or at least I love the photos I've seen of it so far.
I like it even more with animal print on top. I stamped using Sally Hansen Insta-Dri "Fast-Lane Fuschia". It's very subtle so you may be able to get away with it as an everyday look.
