Sheer Style
After all the wild and crazy polishes we've been seeing (and wearing)—raucous red, glaring green, startling cyan—a transparent look, like you get with YSL Beauté La Laque Couture Pop Water ($27;, feels as fresh as a fall morning. One coat in any of the four shades: (clockwise from top: Orange Drop, Fuchsia Rain, Rouge Wet and Rose Splash) gives nails a translucent blush; add another coat or two to deepen the color.
