I've been after a proper 'Cadburys' purple polish for a while now, and I think I have finally found it. It's properly glossy and deep and yet bright at the same time. I love it.
However, as with all Barry M polishes, it chips like a mother. I get one day's wear out of Barry M, max, before it starts to chip. Annoying. But the ones I have are among my favourite polishes in terms of the colour, so I just deal with it. Like it's a big deal!
