What to use: Oval eyes can pull off pretty much any color, but try earthy gray or brown shades to contour the crease and enhance your eye shape, Stern says.

How to use it: You can work your magic with this eye-widening trick: Starting from the inner corner of your eye, draw a thin line of eyeliner that gets thicker towards the middle of the eye and back to thin once you reach the outer corner. Works like a charm.

What NOT to do: Use liner on your lower lashes. If your oval eyes are on the smaller side, skip the lower liner. Just curl your lashes and apply at least two coats of mascara.
