I haven't had much good to say about MAC polish since the Style Black Collection. A few collections have come and gone without me mentioning them, because they were frankly boring crap.
But I picked up MAC Blue India from the Give Me Liberty of London Collection and I really like it. It's a great blue/Grey creme, One coat perfect, and I don't have anything like it! A winner! The other polish in this collection is Vestral White, a boring rerelease. If you can't find WHITE CREME cheaper than this, turn in your polish brush, please.
