I don't usually wear dark colors on my nails during spring, but the weather has been really gloomy lately, so I decided to match my nail color to the atmosphere outside. The name of the nail polish is 'Factory Grey'. I got it at American Apparel a few years ago, and I'm really satisfied with it. It goes at least four days without chipping and is DBP, toluene and formaldehyde free. You can get it here.
