Metallics are having a moment. If you need convincing, look to Emma Roberts, Jennifer Hudson, Julianna Margulies, and Vanessa Hudgens for proof! Roberts, Margulies, and Hudson all stepped out wearing the classic metallics—silver, gold and copper—while Hudgens opted for a shimmery purple. Metallic nail polishes tend to show flaws more than opaque polishes, so buff your digits before lacquering up, and apply the polish with a smooth and steady hand. Swipe on three even coats per nail, layer on your favorite top coat to prevent fading, and shine on! In need of more manicure inspiration?
