This is OPI Jade Is The New Black, from the Hong Kong collection. Apologies for the lack of clean up, but I wanted to get a shot while there is decent light outside to pick the colour up properly. This is a slightly faded bluish jade green cream. Gorgeous colour, but I did find it a little draggy to apply. I got good coverage with two coats, as pictured.
I bought mine from Selfridges, because I was too impatient to wait and order online, but OPI is available from e-tailers for less than the £10 I paid for mine.
