Lately, the most fetching polishes are vibrant, bright…and see-through. “These formulas are like lip tints: You put them on for a subtle wash of color without a big commitment,” says Elle, a celebrity manicurist in New York City. We’re especially loving these YSL La Laque Couture Pop Water Translucent Nail Lacquers ($27 each), glossy stains that come in shades such as red, fuchsia, pink and orange. Paint on a single coat for a barely there glaze; double up to go bolder. Or, to enhance an opaque polish, layer one on top for a fluorescent effect.
