It’s hard to come between me and my beloved greige nail polish, but this season, some new lacquers are tempting me to mix things up. Like Pierre Hardy’s genius shoes, the dozen polishes he created with fellow Frenchman François Nars are sold in pairs ($29, narscosmetics.com), and each combo is inspired by one of his designs. My favorite is a Belle du Jour–esque duo of pale gold and camel called Easy Walking (right center and bottom). Still, no matter how enamored I am with a hue when first applied, I’m often over it by the next morning. Lately, rather than starting from scratch, I’ve been layering on a coat of RGB’s Highlight (top right, $18, rgbcosmetics.com), which adds a pearly warmth over polish. And if I really want statement nails, I dip my brush into OPI’s When Monkeys Fly! (above, left, $9, opi.com), which blings things up with gold and silver flecks floating in a clear topcoat (inset). The best part: No one believes it’s a DIY job.
