This color was originally from last fall's Vintage Vixen collection by China Glaze. It's a mushroomy brown taupe with a gold shimmer in it.
I just recently bought a nail polish from Butter London that's very similar to this but this is darker I think.
I actually haven't compared the two together side by side.
I love this polish because it's a great dark neutral but has a little bit of spice to it. OPI's You Don't Know Jacques! is a similar color but is just a plain creme. The gold shimmer in this polish makes it so much more interesting without going over the top.
The formula on this is pretty good. It's pretty opaque but not annoying opaque. This is 3 coats. I used Zoya's Get Even Ridge Filler as a base coat and the Sally Hansen dry fast top coat.
