After filming was completed, Stewart was allowed to keep all of the clothes which were recreations of the clothes worn in real life by Diana, the ex-wife of Prince Charles and mother of Prince William and Prince Harry who died in August 1997 at the age of 36.
In an interview with Slant, Stewart revealed, “Jacqueline gave me like all the clothes. Is that Robert De Niro keeping everything he ever touched in a movie or something? Or maybe it’s Jack Nicholson.
“One of the bigwigs always does that. I usually don’t take stuff either because you think you’re going to want it because you’re so attached to it then, but then you can’t just have that weird little treasure box of I don’t know. I used to say, ‘I’ll leave this here.’ But I have almost every piece of my wardrobe that I wore in the movie because she wanted to give it to me. She was like, ‘It’s yours. I do not need it.””
“I was like, ‘This is wild.’ So I have all my stuff.”
Stewart has nothing but praise for Jacqueline’s work
The ‘Twilight Saga’ star said, “She creates clothes that aren’t costumes, even though they tell their own story. They have incredible integrity. Everything is real. Every pocket is real. The way she telling her story with the clothes too is not something she ever articulates.
“I did an interview with her recently. I moderated a QA with her. She really wants other people to have the experience and not exactly express her full intent. But that intent is so specific, and it’s always there, every color choice, every moment.
“Even though it’s like she’s so able to pivot, in the moment, and the film unfolds day by day, and it’s not always perfect, but her instincts are that of a true artist. She loves what she does, and she is absolutely a virtuoso… costume designer. One of the best I’ve ever worked with in my entire life.
‘Spencer’ is a fictionalized reimagining of the Princess of Wales’ life and marriage to Charles, 73, and is loosely based on a tense family Christmas Diana spent with her in-laws, including Queen Elizabeth, in 1991.
The name “Spencer” is derived from the Spencer tiara that adorned Diana’s head on her wedding day to Prince Charles. The Royal Tiara was on loan to the Princess from the Queen’s personal collection.
