Here is Essie's "Fair Game" polish from their Resort collection which was released last year. It is a nice metallic greyish blue. I've had the polish for a year now and I've used it quite a bit. The formula was great when I first got it, but I need to get some thinner to put in it; it's gotten a little thick over time.
Metallic polishes were 'in' last year, I hope that trend comes back... :)
