Summerville explains that there wasn't much in the book about Salander's look except that her clothing is dark and she's a natural redhead (hence the red merkin she wears in the film's nude scenes) who dyes her hair black.
"It was important for all her clothing to seem very authentic, nothing brand new," the costume designer says. "Like she could disappear into the shadows and didn't call attention to herself." However, there's one shirt that might get her noticed. One of our favorite costumes is the ripped T Lisbeth wears when Mikael comes to her apartment. It reads (pardon our French) "F--k You, You F--king F--k."
