Skull & Glossbones is part of OPI's 2011 Pirates of The Caribbean Collection. Now, I think this is a polish that has been swatched a million times by a million people, but it's one of my favourites in my collection, so I'm going to do it anyway! I love using it as a base for nail art, or just on its own. It's one of those "anytime" polishes that can be worn whenever, because it's neutral and goes with everything.
The colour is a very light, creme grey. I find it applies a little streaky, but after 2-3 coats you'll have an even, glossy finish. The colour is slightly darker in the shade (see below).
I added a bit of completely random nail art when I got bored.
The green is Rimmel - Green With Envy, and the blue is Collection 2000 - Show Off.
