Jack Schlossberg Slams Julia Fox’s Bloody Jackie Kennedy Halloween Costume

Jack Schlossberg is disappointed with the way Julia Fox chose to celebrate Halloween.

The 32-year-old grandson of President John F. Kennedy criticized Fox, 35, after he attended a party Oct. 30 wearing a blood-splattered costume of former first lady Jackie Kennedy following her husband’s assassination.

Fox donned a replica of the famous pink Chanel suit that Jackie wore on November 22, 1963 – the day Lee Harvey Oswald fatally shot JFK as he and his wife rode in a motorcade through Dallas.

“Julia Fox glorifying political violence is disgusting, desperate and dangerous,” Schlossberg responded in an article on X on Friday, October 31. “I’m sure his late grandmother would agree.”

Schlossberg’s remark was posted a minute before Fox shared more context about his costume choice in a lengthy Instagram post.

“I’m dressed as Jackie Kennedy in a pink suit. Not as a costume, but as a statement,” Fox wrote.

“When her husband was murdered, she refused to take off her blood-stained clothes, saying, ‘I want them to see what they have done.’ The image of the delicate pink suit splattered with blood is one of the most haunting juxtapositions in modern history,” she continued. “Beauty and horror. Aptitude and devastation.”

“Her decision not to change her clothes, even after being encouraged to do so, was an extraordinary act of courage,” Fox said. “It was at once a performance, a protest and a mourning. A woman using image and grace as a weapon to denounce brutality. It’s about trauma, power and the way femininity itself is a form of resistance. Long live Jackie O ♥️”

As Fox noted, Jackie remained in the costume after her husband’s assassination, even after she was presented with another option to wear. The former first lady was photographed in the outfit next to new President Lyndon B. Johnson right after JFK’s death.

“They actually had another dress ready for her and she refused,” historian Steve Gillon told PEOPLE in November 2022.

“She came out in her blood-stained suit and stood next to Lyndon Johnson. Despite these horrible circumstances, she was willing to take a photo because she understood what continuity of government meant to the nation,” Gillon said.

The dress was never cleaned after the president’s death and was eventually sent to the National Archives – still bloodied – around July 1964. The dress remains there today.

Schlossberg recently defended his late grandmother in response to President Donald Trump’s plan to demolish parts of the historic Rose Garden next to the West Wing and the namesake Jacqueline Kennedy Garden next to the East Wing.

After Trump altered the Kennedy-era gardens as part of his plan to create a new $300 million patio and ballroom, Schlossberg spoke out on Instagram.

“My grandmother saw America in color – Trump sees in black and white,” he said. “Where she planted flowers, he poured concrete.”

“She brought the White House to life, because our monuments should inspire and grow with our country,” he continued. “Its rose garden is gone, but the spirit of the Kennedy White House lives on – in the young at heart, the strong in spirit, and in a new generation answering the call to service.”

He concluded: “A year from now, we will have our last chance to stop Trump. History is watching us. We need leaders who are courageous, convinced and truly concerned.”
