This is a guaranteed no-fail look, perfect for everyday wear or for pairing with a bright lip. To get it:
Step 1: Apply an eyelid primer first if your eyeliner tends to transfer to your lids throughout the day. Then apply foundation on your eyelids and under your eye. (Tip: If you use eye cream, wait for it to fully absorb before applying primer or foundation.)
Step 2: Lightly dab and blend stick concealer, which tends to give thicker coverage, on the inner eye corner and over any dark circles. Set with translucent powder.
Step 3: Apply a champagne-colored or shimmery gold shadow like Padma Lakshmi's to the base of your lids. Blend along the inner corners and under your brow bones.
Step 4: Skip liner if you want a more natural look. But if you're looking for more height and definition, draw a fine line as close as possible to your upper lashline with a sharp, black pencil liner. (Try COVERGIRL Perfect Point Plus Eyeliner, $5.79.) If you have monolids, you may have to play with how far up you draw the line for it to show when your eyes are open.
Step 5: Curl your lashes using a metal eyelash curler. Make sure to walk out the curler so that you don't end up with L-shaped lashes. Step 6: Apply several coats of black mascara immediately after curling. Opt for a waterproof mascara, which has a lighter formula and a drier consistency that helps set your lashes' curl, says Babaian.

• If your eyes are close-set, extend your liner slightly at the outer corner to draw your eyes farther out.
• If you have monolids, thin lids, or oily lids, use a waterproof liner to prevent smudging.
• Asymmetrical eyes like Lucy Liu's are a common issue with monolids, says Babaian. If one eye is noticeably smaller than the other, apply the liner a tad thicker on the smaller eye so they look even when your eyes are open. Also, curl your lashes more on the monolid eye. Curling your lashes helps push the eye open, making it look bigger.

This classic smoky eye look, definitely a do for nights out, is easy and works on every eye shape. To get it:

Step 1: Apply an eyelid primer. Then apply foundation on your eyelids and under your eye.
Step 2: Lightly dab and blend illuminating cream concealer on the inner eye corners and over dark circles. Set with translucent powder.
Step 3: Apply black waterproof liner around your eye, or a metallic colored liner for a slightly funkier vibe like Olivia Munn's. Line your inner rims and wing the liner ever so slightly on the outer corners. Using the smudger end of your liner, or a separate smudger brush, blend your liner outward all the way around your eye.
Step 4: Using another smudger brush, go over your liner with a metallic eyeshadow to bump up the intensity, if desired.
Step 5: Curl lashes and apply up to 10 coats of mascara for more va-va-voom. (Try COVERGIRL LashExact Waterproof Mascara, $6.99.)

• If you have small eyes, be careful when lining your lower lid with dark colors. "If you only line the lower inner rim, it makes the eye seem smaller," says Babaian. "So you must smudge [the line] out, which makes the eye look larger."

• If you have round eyes and you want to lengthen them, draw your shadow into a V shape slightly at the outer corners, toward your temples.
• If you have narrow eyes and you want to widen them, add a strip of false lashes like Nicole Scherzinger did here.
• To keep the attention on your eyes, don't do a bright, bold lip. Instead, keep your lips light and simple.

A cross between a cat eye and a smoky eye, this dramatic look is day-friendly but definitely makes a statement. To get the look:

Step 1: Apply an eyelid primer. Apply foundation on your eyelids and under your eye.
Step 2: Dab and blend concealer on the inner eye corner and over any dark circles. Set with translucent powder.
Step 3: Apply a matte or slightly shimmery bone or cool gray shadow all over your lid. Then carefully use a smudger brush to apply black or charcoal gray shadow to the base of your lids, like Yin Chang did here. Blend into the crease. If you don't have a crease, make sure your first shadow doesn't go beyond the midpoint of your lid.
Step 4: For a rich effect, line your eyes with a black waterproof liquid liner (try COVERGIRL Liquiline Blast Eyeliner, $6) or a liner brush dipped in gel/cream liner. Draw a line along the upper lashline, extending it upward at a 45-degree angle. The thickness of the line is up to you; the more pressure you use, the thicker it will be.
Step 5: Close your eyes and wait for your liner to dry completely before blinking.
Step 6: Curl lashes and apply up to 10 coats of black mascara, or add false lashes.
