Foolproof color: Rachel Zoe's navy liner

If you've caught even a snippet of this season's Rachel Zoe Project on Bravo, you have probably noticed one of the fashion stylist's mainstay accessories of late: her navy blue eyeliner. For 'brown eyed girls' like Zoe, navy eyeliner highlights and brightens the eye area, creating a subtle but striking contrast to the darker color of the iris. For individuals with lighter eyes, navy eyeliner can often make the subtle colors in your eye come to the forefront. Navy transitions well into the spring, providing a similar effect as black eyeliner without looking harsh and overdone. Take a cue from stylist and designer Zoe -- shop the navy blue favorites below.
