I only have one Q polish in my entire stash, and she is a beauty. Butter London Queen Vic, is a gorgeous plummy color with lots of pink in it. It kind of changes with the light. It can look anything from plum to maroon depending on the light.
Formula on this was the usual amazingness that is Butter London. It was pretty opaque in one coat but I did two out of habit. I would have been safe with one thicker coat. This also dried really shiny without topcoat! These swatches are two coats with a coat of Seche Vite.
