I am so in love with Butter London's Mum's the Word Patent Shine 10x! I've worn it for a month now.  It has a lot of good stuff going for it besides the colour.  It goes on very smoothly so no streaks, brush is the right size, the actual polish lasts and lasts! The colour also looks so good against my skin and at times looks lighter or slightly darker depending on the light.  Wonderful stuff.

Chinchilly by nail polish stalwart Essie, is the best slate grey to be made as far as I am concerned! Another brilliant formulation, lasts and lasts, I wore this so much I am onto my third bottle! A great urban and chic colour choice.
