1. To create a gorgeous nighttime look, use light, medium and dark eyeshadow shades in graduated tones. Apply the dark shade along your lash line, the medium shade on the crease, and a light shade up to the eyebrow bone but not beyond. Soften and blend any hard edges so one color seems to melt into the next.
2. To open up your eyes so that they appear livelier, place a dot of a light shadow in the inner corner of each eye.
3. For a sexy, smoky effect, trace the upper and lower lashes with a dark shadow then smudge with a blending brush. To optimize the look, this can also be done over eyeliner.
