Catrice's '59 First Class Up-Grape' is a recent addition to my collection and the colour is an absolute stunner. The brush is an absolute nightmare, however. A fine formula as we've come to expect, and it covered in two coats. The brush is really the only downside, it's poorly shaped and the bristles that stick out there damage your polish more than it applies it, so it takes a little doing.
But the colour - the colour! My pictures are nowhere near to doing it justice. It's a gorgeous dark aubergine shade with a shimmer that's just right. If it wasn't for the brush, I'd have nothing but praise.
