Jack Schlossberg Calls Julia Fox's Jackie Kennedy Costume 'Disgusting'
Jack Schlossberg Hey Julia, You Should've Picked A Different Costume!
Julia Fox's choice of Halloween costume might have been embraced by her fans ... but Jack Schlossberg wasn't one of them.
Julia decided to dress up as Jackie Kennedy Onassis -- Jack's grandmother -- for The Cursed Amulet's Halloween party in New York City on Thursday night.
We know it sounds innocent enough, but get this -- Julia opted for a version of the former first lady's blood-soaked pink suit Jackie wore on November 22, 1963, when her husband, John F. Kennedy, was assassinated in Dallas, Texas.
Jack described Julia's look -- which she described as "Jackie O-Nasty" in an interview with Vulture -- as "disgusting, desperate and dangerous" on his X account.
Jack said Julia was "glorifying political violence" by imitating his grandmother during one of her lowest moments.
Julia Fox glorifying political violence is disgusting, desperate and dangerous. I’m sure her late grandmother would agree.

Julia explained the reasoning behind her decision in an Instagram post, saying she was trying to make a "statement" with the costume.
Julie wrote that Jackie's choice to stay in her bloodied clothes in the hours after her husband's murder was her way of "weaponizing image and grace to expose brutality," pointing out Jackie "refused to change out of her blood-stained clothes, saying, ‘I want them to see what they’ve done.’"
