Lily James has "embraced" wearing extravagant gowns.
The 27-year-old actress - who became the face of Burberry's new fragrance 'My Burberry' earlier this year - has admitted she is not used to wearing elegant gowns, but believes she has "grown into" the glamorous style because of her acting career.
Speaking on ITV's 'Lorraine' on Wednesday (02.11.16), the 'Downton Abbey' star said: "I've sort of grown into it, having these wonderful dresses that have been custom designed; now I have really embraced it.
"I think that's because I dress up a lot in work."
However, Lily has revealed she considers herself to be more of a "dress-down girl".
She explained: "I am more of a dress-down girl.
"So you know, when I'm at home I tend to wear jeans and converses."
Meanwhile, Lily has been cast in the role of pilot and the late Burberry's founder's, Thomas Burberry, love interest Betty Dawson in the luxury brand's Christmas campaign, which is a short film 'The Tale of Thomas Burberry' based on the creative mastermind, who died in 1926, and was unveiled on Tuesday (01.11.16).
And the star has revealed she loves her character in the video because she's "got time" to apply a slick of rouge lipstick prior to jetting off.
She explained: "The script is really beautiful, aside from the fact it's a wonderful story... She moved from Croydon to Capetown and broke a world record, she's flown at the way and she's still got time to put on red lipstick."
And Lily has revealed she had a "wonderful time" shooting the clip to celebrate Thomas' life and the brand's 160th anniversary alongside Sienna Miller, Domhnall Gleeson and Dominic West
When asked about the cast, she said: "Brilliant. I've never worked with them before, I mean I know Dom West very well, but Domhnall and Sienna, I've never worked with them before, so it was a real pleasure and was just brilliant so I had such a wonderful time."
