In the end I picked Purple Ash and Grace Green - there was only one of each left! The lipgloss shade is called Violet Cream.
Here's the two colours without any topcoat:
..and the new Barry M Instant Nail Effects over the top:
Both colours, I think, are incredibly pretty and autumnal! Totally loving brownish-purple hues at the moment and for once the green doesn't make my skin look sick which can only be a good thing! I will probably waste some more of my student loan on the other colours.. you'll have to persuade me to do so though (yeah right)!
