My nails today are so plain... but I haven't used a metallic polish in a long time so it's a neat change. They're plain, but so shiny in real life that I don't think they need anything else done to them.
I used two coats of
Essie - Nothing Else Metals. It's funny because I see a bunch of other people using metallic polishes for their 31 day nail art challenges, and I couldn't have better timing :P
