I don't know what it is about this polish, because it doesn't really look like anything special and it doesn't stand out on its own, but I absolutely love it!
OPI Copper Mountain Copper
This is the re-released version that came out with OPI's Colorcopia Collection. It is a lovely mix of brown/red/pink with a slightly frosty finish. It was beautifully opaque in two coats, and applied wonderfully. It reminds me of a lighter version of China Glaze's Fashionably Late. It is total gorgeousness. Loves it!
