Leave it to Rihanna [1], the queen bee of nail polish, to take an opaque, shimmery metallic color to the next level. Chrome is more of a powerful gold-and-silver version of its true silver sister gunmetal [2] and it is also much darker than pale gray [3].
I still can't quite believe that metallic nails are still this much of a sensation. Even LC can't get enough of glittery metallic nails [4]! Below are a couple of rocker-cool chrome polish suggestions for Summer. Enjoy!

Essie Steel-ing the Scene [5] ($8) is a bronzey-pewter (effectively a chrome) shade of nail polish that contains flecks and packs a lot of punch. For those of you who are too shy to wear this on your nails, it makes for a great toenail color.
Tropez Super Pearl Nail Enamel in Black Pearl [6] ($1.99) is a deep, opaque gray that looks amazing with one sheer coat of Tini Beauty's Gold Haze Topper [7] as a topcoat. The result is a metallic, high-shine glossy finish — and the best part is that it's a unique color!
