As she twirls around in a double-breasted black dress Natalie Portman is keen to show her girly side.
"It's McQueen!" she laughs, as she sits down demurely, showing off an almost regal composure that hasn't wavered after several days on the publicity trail.
Ever since the Toronto Film Festival in September, the petite 35-year-old has been flooded with praise for her role in Jackie, playing one of America's most famous first ladies.
Now, six years after her Oscar win for Black Swan, she's once again an Oscar favourite, despite missing out on the Golden Globe earlier this week.
Told in flashbacks during her interview with Life magazine's Theodore H White (Billy Crudup) at the Kennedy compound in Hyannis Port, Jackie deals with a very specific time period, the week surrounding President John F Kennedy's assassination.
It was November 22, 1963, when the first lady was sat next to her husband in an open-topped limousine as the president was fatally shot, dying in her lap. As we see in the film, Jackie wore the blood-splattered pink Chanel suit during the swearing-in of Lyndon B Johnson and for the flight back to Washington with her husband's body.
Portman, who is about to give birth to her second child with her French husband Benjamin Millepied, her choreographer on Black Swan, could only imagine what it was like for Jackie to not only deal with the tragedy but to have the world's media focused on her as she organised the funeral.
"There were so many things that she was dealing with, everything was in question and it happened in such a sudden, violent, tragic and traumatic way," Portman says. "I think it's shocking when those questions come up so suddenly when the day before her biggest question was picking out the colour of the wallpaper.
"One of the things that I focused on was her determination to author her own story and to be the author of her legacy and that of her husband. She was very aware of splitting herself between who the public wanted her to be and who she really was."
Portman was keen to give Jackie her due. Before JFK became president she had been thought of as a liability, the actress notes.
"On the campaign trail they used to hide her because they thought she wasn't relatable for women at home. People thought she was a snob. They said, 'Oh she speaks French, she wears these fancy clothes and she does her hair funny'. Then all of a sudden as First Lady it became a trend. Everyone started wearing their hair like that and women started taking French classes."
Portman exerts just about every acting muscle to embody the US icon.
"This was the most challenging role because everyone had an idea of her," Portman notes. "I've never played a character like that before."
