Jennifer Aniston: 'The Good Girl'

Aniston in "The Good Girl"

(InStyle) -- In "The Good Girl," Jennifer Aniston strays from her trendy It Girl image to play dowdy discount store cashier Justine.

Stuck in a nowhere job and married to a deadbeat, Justine is dealing with blues deeper than her relaxed-fit denim jeans. So when she sees a soul mate and sexual escape in the new checkout boy Holden (Jake Gyllenhaal), she chooses passion over piety, no matter how reckless the romance.

"She's an intelligent, warm-hearted woman, but she finds love in all the wrong places," says makeup artist Carol Schwartz, who gave Aniston a pretty but ordinary look to suit her character's small-town Texas life. "Justine works behind the cosmetics counter, but I didn't want to make her look like she's at a Chanel counter," says Schwartz. "She's selling cheap stuff."

To transform Aniston's straight Rachel hair into Justine's wavy, deconstructed do, hairstylist Daniel Curet used products that left her locks looking a little dull and matte. "We wanted to break away from her "Friends" look," says Curet. "We didn't want her hair to be shiny because it would read too styled."

To give her a casual, "not so polished" look, Curet first applied TIGI Bed Head Uptight Heat Activated Curl Maker to Aniston's damp tresses and then scrunched hair with his hands. Next he used double-thong clips to crimp and separate her locks. "Nothing too formed and defined," he says. After adding some more spray and diffusing hair dry he applied KMS Hair Play Molding Paste. Finally, he pulled hair back into a ponytail, folding it underneath into a messy bun.

For a natural look, Schwartz simply swept a light coat of MAC eye shadow in Shroom on Aniston's lids. Then using MAC Crème liner in dark brown she drew a thin line, very lightly flicked up at the corner, along the top lash lines. To balance out her eyes, she first dotted then softly smudged MAC Shroom on the bottom lash lines using a tiny brush. The final touch: L'Oréal Lash Out mascara in black applied to top lashes only, to keep her from looking too "va-voom."

Face

"I tried to keep her as low-key as possible," says Schwartz of Justine's unglamorous look. "I wanted her to look a little tired and washed-out, so I didn't use a lot of corrective makeup under her eyes." Schwartz began with Clinique Balanced Makeup Base in Honeyed Beige, a medium-beige foundation that complemented Aniston's tanned skin, followed by a dusting of Chanel Natural Finish Translucent pressed powder. For a slight dewy glow, she dabbed cheek apples with Lorac Sheer Wash in Sheer Luck, a translucent rose color. Says Schwartz, "It's very sheer and natural, and gave her just a hint of color."

Lips

After moisturizing lips with Kiehl's Baby lip balm, Schwartz used a brush to line Aniston's lips with Chanel Face Colour Pencil in Muscat. "It's a lovely natural pink color," says Schwartz. She then dotted on more color and blended with the brush "so you're not aware that the lips are lined."
