You have almond eyes if ... Your eyes are perfectly symmetrical with very slightly upswept outer corners.

Think: Beyoncé

The challenge: This is considered the most versatile shape for any look (hardly a challenge), so focus on increasing the depth and intensity of your looks.

Your makeup look: To make eyes appear larger, tightly line the upper lashline with a dark matte shade only. Skip eyeliner on the lower lashline -- it can make eyes look smaller.

You have round eyes if ... The width and height of your eyes are nearly the same. Sometimes you can see white underneath your iris.

Think: Christina Ricci

The challenge: Eyes can look shorter and lose some of their width.

Your makeup look: Using a dark shade, line your upper lashline, extending out and up at the outer corner to elongate the width of the eye.
