Knackered

This is Butter London Knackered:

It's one of those shifty sheer things that I tend to wear as a top-coat - it looks in the swatch like you might possibly be able to get it close to opaque, at least, but I won't swear to that. I'm not 100% sure I've ever worn this, actually. But it's interesting. It almost looks like it's got a blue-violet undertone, although it's hard to be sure. And it has some bits of sparkle in there, too.
