If anyone can play a stunning beauty who doesn't age, it's Blake Lively. And the actress does just that in her upcoming flick The Age of Adaline, which tells the story of a 29-year-old woman named Adaline Bowman, who, born in the early 1900s, never ages again after a mysterious car accident. As Adaline lives through the 20th century, she may not grow older, but she does switch up her look—as evidenced in one of nine Adaline Through the Ages ‘Character Posters.’

The image above captures the character in 1943, and Academy Award–winning costume designer Angus Strathie worked to make Adaline's appearance as true to the times as possible. "I love this look because it reminds me of Lauren Bacall in How to Marry a Millionaire," the film's director Lee Toland Krieger tells InStyle. "Like Bacall, Blake is an indomitable beauty. At this point in our story, she's on the run with a secret, so it was critical her look felt strong and fearless—a look that would be fitting for a woman who was on her own, forced to navigate through a world dominated by men."

Aside from Lively's wardrobe in the film (which mostly consists of pieces by Gucci), hair and makeup were also a crucial factor in keeping her overall style authentic.

"There are general characteristics in makeup, hair and style in each era and we definitely got to explore them all in this movie," says Monica Huppert, the movie's makeup artist. "We wanted Adaline to have her own style so I decided to keep a lot of the same colors in Adaline's palette throughout the decades making only adjustments to help tell sell the period, for example, the shape of the 1940’s brows and lips."

To get the right mix, Huppert used products by L'Oreal, including Infallible Pro-Last Lipcolor in Infallible Red ($13; and Visible Lift Blur Blush in Soft Peach ($13; "The beauty about Blake Lively, who played Adaline, is she isn't afraid to try things. If anything she would push me to take things further, she wasn't afraid if it was right for the character.”
