Taupe eyeliner is like the black blazer of our makeup wardrobe: It looks great with everything and end up reaching for it almost every day. When we're in a rush in the morning or after a workout, or are sporting a punchy lip color or blush, we always smudge creamy nude Make Up For Ever Professional Aqua Eyes Eyeliner in 24L around our eyes. It's literally foolproof— you cannot mess it up— and gives eyes just enough hazy definition without looking like makeup. And it doesn't budge all day long— truly perfection in a pencil. Tell us: What's your go-to neutral eye color?
