This is Boho Blues by China Glaze. Two coats, good formula and a gorgeous cornflower blue colour. Unfortunately I have two dupes for this one, namely Rimmel 60 seconds "Mind The Gap, Victoria" and Barry M "Blueberry".
I stamped over Boho Blues with Konad White using an image from stamping plate "Lily Anna 13".
