The film's costume designer, Madeline Fontaine, was tasked with recreating some of Jackie's most iconic looks — like this two-piece red wool dress.
According to the film's production notes, Fontaine even tracked down some of the companies that made fabrics for the First Lady back in the 1960s.

Here's the how the real Jackie looked in the ensemble.
She wore it during a televised tour of the White House in 1962.
Even when the designers didn't replicate a famous outfit, they still stayed true to Jackie's overarching sense of style. Here's Portman in a regal satin gown...
Fontaine took great care when replicating the film's most important costume: The pink suit and pillbox hat Jackie wore the day her husband was assassinated.
The design team created five different version of the suit just to make sure the shade of pink was exactly right.

"It was truly impressive to see Natalie in the suit the first time on set,” Fontaine said in the film's production notes. “She took on the aura of Jackie.”
