Eyeliner is not your basic makeup staple. Not only can it transform your look from subtle to dramatic, but it can also appear to alter the shape of your eyes, creating the illusion that they're bigger, more lifted, wider or rounder.

We consulted with makeup artist Emily Oliver to find out which eyeliner looks are right for you, plus we rounded up all of the Instagram inspo you need, ahead.
