Ever wondered what color the Dior offices in Paris's Avenue Montaigne are? Well, now you can see it for yourself without going to the City of Lights, because Dior's launched a polish called Gris Montaigne ($21) that mimics the hue of their famed headquarters. For an exterior paint-inspired shade, it's very pretty, although I also wouldn't say that a mid-gray polish in this family is exactly hard to find, either. What do you think? Would you wear this piece of Paris on your fingers?
