You don't have to be a French actress to rock gorgeous cat-eye makeup—which celebs like Rihanna, Angelina Jolie and Zoe Saldana know very well. The key to getting this sultry, edgy look? A steady hand and a thin, heavily pigmented liquid liner, like the new NARS Eyeliner Stylo ($27). Available in three shades, the marker-style tip gives us grade school flashbacks, but the silky, flawless results are anything but juvenile. Meow, indeed.
