The "Layer Cake" star said that Marlowe is brutally honest when it comes to style tips.
"She'll tell me what to wear and she'll tell me if I look awful," added the 37-year-old.
Miller said that her daughter had a clear sense of style, adding: "She doesn't let me dress her. Before my child could speak I could dress her. I loved having this little dolly I could put clothes on. But now I cannot."
She welcomed her daughter with former fiance Tom Sturridge back in 2012. She was in a relationship with Sturridge, 33, from 2011 till 2015.
Earlier this year, the "American Sniper" actress told PEOPLE outlet: "My daughter challenges me and is a real mirror. When you are raising a child you see aspects of your character in that person, reflected back, and it's the most loving, intense relationship that I have. There's nowhere to hide."
