Today I am posting about one of my favourite polishes at the moment. This is OPI's 'Her Majesty's Secret Service' from their recent Skyfall collection. It's such a gorgeous colour, but so hard to describe! I would say that it is a dark metallic gray base with teal, lilac and holographic shimmer running through it. There is a similar colour in the collection that came in the mini Skyfall set, although it is more warm toned. I love this colour, so if you can still find it - it's worth checking out!
