This is a new acquisition, Barry M's Dusky Mauve. Initially, I thought that in the bottle it looks very like Mushroom, but then when you lift the bottle and move it around in the light, it's obvious that there is a lot of purple shimmer in there too.
This is two coats with topcoat. The formula is typical Barry M - smooth, dries well, covers really well, and very glossy. I was a bit disappointed with how little purple there is once this is on the nails - to me this looks mainly like a dark putty-ish grey colour. There is a clear purple tinge in certain lights and certain movements, but it's not nearly as obvious as it is in the bottle.
My skin is terrible at the moment - it looks bad here, but the reason I haven't posted in a while is that it was looking ten times worse than this for the last week! My skin is very dry and cracked, and I have had a few little cuts and scratches too. I blame the cold weather! I'm going to have a bit of pampering this weekend.
