Butter London's The Old Bill is described as a burnished copper with an antique patina. On the Butter London website, it definitely looks coppery. In person, it's trickier. Inside under incandescen lights it is a decidedly warm copper with a tinge of pink. In sunlight and under fluorescent daylight bulbs it is often straight up gold with almost no hint of copper.
I picked this up in a MUA swap a couple of weeks ago. It wears well on me. I get some chipping after about a day and a half, but I can wear it for up to a week before it's so bad (by my standards) that I have to remove it completely.

So I was really wanting this polish to be a rose gold - I'm not sure why. But it isn't. So for that reason alone, I'm a little underwhelmed with it. If you're looking for a warm gold polish, it's great. I just wasn't looking for that.
The formula applied very smoothly. It was mostly opaque in one coat, but I always apply two coats regardless along with a base coat and top coat. As I've said before, I adore the packaging on the Butter London polishes and that is absolutely one of the reasons I am so drawn to the brand.
Like all Butter London polishes, it contains 11mL of product and retails for $14 wherever Butter London is sold.
