Oscars 2012: The Best Hair and Makeup Looks

Michelle Williams

"When I saw the dress, something about that gorgeous color just reminded me of a flower," celebrity makeup artist Angelina Levin told Us of her inspiration for the actress' look. To get the perfect purpley-pink lip color, Levin mixed two shades of Chanel Rouge Coco Lip Colour: Paradis and Destineé

Jessica Chastain

To give The Help star a natural glow, makeup artist Mai Quynh applied mark Just Pinched Instant Blush Tint in Peachy topped with mark Good Glowing Custom Pick Powder Blush in Cameo Glo. On her eyes, she used a mix of gold and copper shadows and liner for a sexy, cat-eye effect.

"I wanted to have a little bit of a retro vibe," Suave Professionals hairstylist Jenny Cho told Us of the wavy half-up style, which featured a sexy bump at the crown.

Natalie Portman

"The dress was amazing, so the inspiration for Natalie's look was 1950's old Hollywood glamour," makeup artist Eileen Kastner-Delago said. To get the perfect lip color, she used Dior Rouge Dior in Rouge Favori and Dior Addict Ultra-Gloss in Pink Trench.

Emma Stone

The Help actress wowed with a bold pink eye look. "I took my inspiration from the exuberant bright fuchsia shade of her dress," said Chanel makeup artist Rachel Goodwin.

To make sure her hair didn't compete with the oversized bow on her Giambattista Valli design, Couture Colour hairstylist Mara Roszak gave Stone a large twisted bun, smoothing on Pequi Oil Treatment for a polished look.

Penelope Cruz

From her retro-inspired, faux bob to her classic makeup, the actress' look was pure Hollywood glamour. Makeup artist Matthew Van Leeuwen used Lancome Color Deisgn Palette in Gris Fatale to create the smoky eye effect.

Rose Byrne

The black sequins on Rose Byrne's Vivienne Westwood dress were so sparkly that makeup artist Maud Leceppe opted for a soft smoky eye (he used Nars Eyeshadow in Lhasa and Coconut Grove).

Her glossy bob looked extra chic, thanks to a deep side-part and quickie bang trim from her stylist Harry Josh.

Tina Fey

"We wanted her to look kind of old Hollywood with a modern twist, makeup artist Gita Bass tells Us Weekly of the 30 Rock star's glowing skin and modified cat eye. As for her hair, the actress rocked a super-size updo.

Shailene Woodley

To complement the high neckline on her white Valentino gown, hairstylist Campbell McAuley for Matrix gave The Descendants star a "textured chignon with a Moroccan twist." For all-night hold, he misted the 'do wit MATRIX Design Pulse Hard Lock Hairspray

Sandra Bullock

"I just went for a glamorous movie star gorgeous" celebrity makeup artist Angela Levin told Us of the radiant look she gave Bullock, using Chanel Quadra Eyeshadow in Enigma and Chanel Rouge Coco Lip Coulour in Mademoiselle topped with Glossimer in Braise.

To enhance the star's shiny brown hair, her stylist David Babaii applied a few drops of his new Miracle Oil Hair Elixir before blow-drying and creating a high ponytail.

Berenice Bejo

The Best Supporting Actress nominee's heavy lined eyes and fresh skin were inspired by Audrey Hepburn, makeup artist Julie Hewitt said. Her braided updo, however, was totally on-trend.

Stacy Keibler

"She wanted to do something modern and classic," Couture Colour hairstylist Peter Savic told Us of Keibler's side-swept waves, which got a dose of Pequi Oil Treatment for extra tons of shine. Makeup artist Melanie Ingelsis complemented the 'do with smoldering eyes and nude lips.
