White polish is the color du jour, says Skyy Hadley, a celebrity manicurist. If your skin is dark, look for sheer hues that are pearly or have a hint of shimmer, like Revlon Nail Enamel in Pure Pearl ($5; at drugstores) and OPI Nail Lacquer in Fit for a Queensland ($8; opi.com).

Fairer types can pull off more opaque tones like Essie Nail Polish in Below the Belt ($8; opi.com). Avoid looking as if you're wearing Wite-Out by staying away from colors that are too matte, and be sure to finish with a super-glossy topcoat.
