I always use eye pencils, never liquid eyeliners. I find it easier to draw the perfect cat eyes with an eye pencil, the chance of error is minimum, and it takes less effort. For this purpose, you need a decent eye pencil with buildable coverage, like this Golden Rose one. You can draw a light cat eye for office days and build it to a dramatic, party-worthy cat eye. My friends usually line up for getting their cat eyes done whenever we are getting ready together for any party or occasions; and that's saying a lot. 😉 Just make sure the pencil is sharpened enough, and you're good to go.
