I find that eyeliner is one of the most important things in my makeup routine, since it can change your look instantly! Of course, you could just line your eyes throughout your lashline and call it a day, but why not go the extra mile and try the oh so popular cat eye. The cat eye is universally flattering because it elongates the shape of your eyes and makes them look bigger and more open. Experiment with the variety of cat eye looks below and see what suits you best! As for your tool of choice, we suggest the Clio Pen Liner in Kill Black, which is a super easy to use, fine tipped pen liner that was practically made for creating cat eye looks.
