The actress' makeup artist, Molly Stern, exclusively told StyleList that the idea for the classic look came from Adams' "incredibly rich teal Marchesa dress."
"The gown walks that line of strong and soft, and is rich like a pastel painting. We reflected that vibe in the makeup with defined features that still allowed her beautiful, natural-looking strawberry-blond softness to come through," said Stern.
After illuminating Adams' peaches-and-cream complexion with YSL Perfect Touch Radiant Brush Foundation, Stern went straight to work on the star's eyes. Lancôme's Color Design 5 Pan Palette in Taupe Craze -- which will launch in February -- was used to blend gunmetal definition up into a sheer champagne highlighter that glinted against the brow bone.
"I gave her some really bold lashes. Usually, I'm all, 'Let's do brown! It's more neutral and fresh!' But tonight, we pulled out the black Hypnôse mascara, and I lined with Le Stylo Waterproof Eyeliner in Minuit. The combination of navy and black brought out the color of her eyes," said Stern.
For lips, Stern mixed a custom blend of two Lancôme lip shades.
"I used two lipsticks because I just can't be normal and use one," laughed Stern. "I first applied Color Design Matte Lipcolor in Stylista, which is this pure raspberry tone. Then I topped with the sheer L'Absolu Nu in Evening Lace for shine," added Stern -- the latter of which will launch in March.
The light Giorgio Armani Sheer Blush in #2 was lastly layered on for a "painterly feel" that emulated the exquisite shading of the gown.
And redheads, listen up: Stern says that if your coloring mimics that of Adams, you should never feel limited by what you can do with your makeup brush.
"I'm a redhead fanatic. The warm skin tone is an ideal palette to play with. It picks up color beautifully. I always feel most free as an artist when I'm working with a redhead."
From Rihanna to Khloé Kardashian, looks like Ms. Stern's calendar will be chock full of work this season.
