Autumn trend : metallic nails

Ok, so I saw different press articles about that, and a lot of celebs wore this style on the red carpet!
And it's actually a good trend that I like, you don't have to push it too much, but keep the style casual with not too long nails (unlike Rihanna's) but anyways, I was looking for the Chanel metallic color nail polish but couldn't find it. So I got the one from Sephora, which is pretty fine too, but you need 2 coats
