Natural/Day Look
1.
Gently rub an eyeshadow primer onto your eyelids and brow bones. Primer makes it so you don't have to stop in front of a mirror every two hours to touch up your makeup, plus it makes for a smooth, clean finish.
2.
Dust your light shade from eyelid to just under the eyebrow. For the most natural look, your shadow shouldn't extend beyond the outer corners of your eyebrows.
3.
Brush your darker shade delicately in the creases of your eyes. Blend the dark color with the light color thoroughly for a seamless, natural look.
Night Look
1.
Night looks generally call for dark or shimmery eye shadows --- you know, the ones that make your eyes glow on the dance floor. Pick two shades that complement your eyes, one neutral and one dark, to start out your smoky makeover.
2.
Apply your light shade from eyelid to eyebrow. Your light shade shouldn't be too noticeable, but for a more dramatic look pick a light color with some serious shimmer. It helps to use an eyeshadow primer on your lids, first, to keep the color from creasing or wearing off.
3.
Using your darker color, press your eyeshadow applicator under your brow bone and brush it inwards.
4.
Blend the deep color with the lighter color along your eyelid for a clean, sexy look. To "smokify" your style, smudge the shadow with your finger and add some dark eyeliner and mascara to both lids.
If you're using two eyeshadow colors that are both dark (a copper and a brown, for instance), apply them only to your eyelid, with one color all over the lid and another color as an accent on the outer or inner corner of the eyes. Leave the area above your crease "naked," since using dark colors above the crease tends to be too much.
