If you have shaky hands (or happen to live in an earthquake-ridden zip code), NARS Eyeliner Stylo ($27) is sure to diminish the blips in your liner look. The felt marker's tip is fine enough to create well-defined eyes that still look natural. But angle the pen on its side, and you'll have a thicker line for more dramatic eyes. With the amount of control this liner offers, you can draw a cat-eye or double-winged look in seconds. The smudge-proof finish is as fluid and shiny as a liquid liner but has the ease of a pencil. And if you're looking to step beyond the typical brown and black colors, good news: this eyeliner also comes in gray and navy for Fall.
