While not all of us can achieve the level of emulation that has us, say -- writing a daily sex column from our NYC apartment and hot-spot hopping at night -- the look between the personality duality can be achieved, very often with some minor alterations to our routine.

So how do we create the nice and naughty looks? We asked the experts.

The looks
Mary Schook (maryschook.com) is a "beauty engineer" on the forefront of the intersection of beauty and well-being. Schook strongly believes in unraveling the mythology around beauty products and practices, and says one can make the same lipstick, liquid liner, mascara and blush and create two entirely opposite moods!

How the looks compare

For the naughty vs nice look, Schook defines them as follows:

Naughty:

Lips: Vixen. Deep red lipstick applied across the lips says you're in charge.

Eyes: Liquid eyeliner smudged around the eye adds mystery, while mascara is applied to the edge of the lashes giving a little bit more of a cat-eye look.

Cheeks: Blush contoured below the cheek bone brings out the diva.

Jessica Simpson does both naughty and nice looks  

Nice:

Lips: Red lipstick tapped across the lip like a stain.

Eyes: Liquid liner applied lightly to the base of the lashes. Mascara is wide-eyed and innocent. Application is mostly at the center of the eyelashes.

Cheeks: Rosy blush is whisked lightly across the apples of the cheeks.

Step by step: Get a sweet look
Monique Powers (moniquepowers.com), a highly-regarded California-based airbrush makeup artist and brow specialist, offers these tips on how to create your inner ingénue or nice girl.

• Start with a foundation primer.
• Follow with a tinted moisturizer or apply your foundation with a sponge for sheer coverage.
• Set with powder and then apply a sheer blush for a soft glow.
• Apply soft eye shadow colors to the lid, and then line the top with a soft brown pencil.
• Follow with a coat of mascara.
• Complete the look with gloss on the lips.

Powers says that if you're going for the innocent look, "Less is always more."

Step by step: Get a hot look
Sexy sirens -- the naughty girls -- are all about inviting lips and smoky eyes.

Monique says the best way to create this alluring look is as follows:

• For smoky eyes, start with a soft shadow to highlight the brow bone area and then sweep an intense color such as brown, grey, or bronze on the lid. Depending on your eye color any rich color will work. The key is to blend, blend, blend -- so that the lines are smooth, and the color looks intense but not harsh.
• Next, line the top of your eyes and underneath the bottom lashes with a corresponding or complimentary eyeliner pencil. To open up the eyes, try extending the eyeliner just a little to elongate the eyes.
• Then, curl your lashes, apply a coat of mascara and to give your eyes a smoldering look, apply false eyelashes.
• For inviting lips, start by lining your lip with a lip pencil, and then follow with a lip gloss that will last.

Robert Jones (simplebeaute.com) creator of Simple Beauté, a web-based company that carries a large variety of makeup tools and accessories (and author of the book Makeup Makeovers) says, "Nothing says 'naughty' quicker than a smoky eye." He advises, though, to pair it with nude lips so as to not overdo the look -- but "a dark, intense lip color will turn up the naughty quota."

Drew Barrymore also can look both naughty and nice

Something in between
For those wanting a less naughty look, Belinda Moss, a professional makeup artist and spokesperson for Softlips, seconds wearing a more subtle shade, such as a metallic brownish lip tint -- a rich color that complements all skin tones and accents your wardrobe.

He also suggests adding false eyelashes and a little extra eyeliner will help create high drama. As for the nice-girl look, Jones says nothing beats a soft flush to your cheek. Go for a soft, shimmery apricot. "No man wants to kiss dark lips -- choose a soft glossy nude." For a flirty-but-innocent look, go with a soft, shimmery taupe eye shadow.

Can the same girl be both naughty and nice? She should be -- and can, as you can see from these celebs here. It's all about prerogative, mood... and a little bit of adulation.
