Make-up was an essential tool used by Carey Mulligan's character in Promising Young Woman.
The British actress plays Cassie in Emerald Fennell's directorial debut, about a young woman desperate to deliver revenge on those she blames for a traumatising event from her past.
Talking about how Cassie operates, Carey revealed in her Harper's Bazaar U.K. cover interview why beauty was so important.
"My character makes up different characters. She goes out in totally different personas, and so make-up is a really important thing," she detailed. "We went from really vast extremes: sort of a proper body-con outfit and scraped-back hair, like a Kardashian look, which was so much fun. And then she plays the sort of young, vulnerable almost teenage girl."
As for what helped her stay in character, the 35-year-old said it all came down to what was on her nails.
"I had this amazing manicure in Promising Young Woman: Each finger was painted a different colour of pastel. It was so pretty; something I could never maintain in my real life, but I really liked having for the film," she smiled.
Promising Young Woman, written, directed and produced by The Crown star Emerald, was recently nominated for four Golden Globe awards; Best Actress in a Motion Picture - Drama, Best Screenplay, Best Director, and Best Motion Picture - Drama.
