You’re probably wondering, what could possibly be new in nail polish? The answer is a brush as thick as your nail. Before today, Yves Saint Laurent’s lacquer was the only polish we’d encountered with a brush thick enough to coat a nail in paint with just one swoosh, but thin enough to easily maneuver. Now, Armani’s following suit with 18 shades of Nail Lacquer ($20) in relatively small bottles with voluptuous brushes that make application so easy you’ll wonder why everyone doesn’t jump on the big brush bandwagon. Our favorite shades? Four Hundred, Armani’s classic red in nail lacquer form, and Black Petrol, a shimmering black navy blue infused with teal. Happy painting!
