In a season of piled-on brooches and statement necklaces, even the most minimalist of women feel pressure to accessorize. But if you're not the type to heap on the baubles, the current wave of metallic nail polishes is a good way to ride the glitz trend without going overboard. Keep the look sharp by, ironically, filing your nails down (that means no talons allowed). Short, rounded shapes show off the shiny new shades best.
