Julia Fox dressed as a blood-stained Jacqueline Kennedy for Halloween

Julia wore a pink suit and matching pillbox hat, mirroring Jackie's double-breasted wool ensemble.

She paired the look with white gloves, a short black wig, and a black handbag.

The outfit appeared splattered with fake blood.

The Uncut Gems star later shared images of her costume on her Instagram Stories.

Jackie's original pink suit became one of the most recognisable images of the tragic day JFK was gunned down.

According to The New York Times, her suit, shoes, handbag and stockings were "blood-covered and folded in a towel" after the shooting.

The blood-stained items were never cleaned and remain preserved at the National Archives and Records Administration facility in Maryland.

The Los Angeles Times reported Jackie's maid, Providencia Paredes, placed the outfit in a bag and sent it to the archives sometime before July 1964.

In the hours after the assassination, Jackie was photographed wearing the same suit while standing beside Vice President Lyndon B. Johnson as he was sworn in as president aboard Air Force One.

Historian Steve Gillon told People magazine in November 2022: "They actually had another dress laid out for her to put on and she refused. She went out in her blood-stained suit and stood next to Lyndon Johnson.

"Despite these horrible circumstances, she was willing to stand for a photo because she understood what it meant for the nation to have continuity in government. She understood that she had a role to play in helping the nation transition to a new president."

Jackie had worn the two-piece suit on at least six previous occasions before her husband's assassination, according to The New York Times.

The suit itself was a Chanel-approved copy made by the New York fashion house Chez Ninon.

The assassination of John F. Kennedy, who was 46, remains one of the most defining events of the 20th century.

In her diary, Lady Bird Johnson - the wife of Lyndon B. Johnson - described the moment she saw Jackie cradling her husband's body in the motorcade.

She wrote: "As we ground to a halt - we were still the third car... I cast one last look over my shoulder and saw in the President's car a bundle of pink, just like a drift of blossoms, lying in the back seat. It was Mrs. Kennedy lying over the President's body.

"Mrs. Kennedy's dress was stained with blood.

"One leg was almost entirely covered with it and her right glove was caked, it was caked with blood - her husband's blood."

Julia's Halloween costume came just weeks before the 62nd anniversary of Kennedy's death and has seen her face a huge backlash online over the outfit choice.

One of her many critics said online: "So tasteless. Tragedy is not a costume."
