Julia Fox didn't dress up as Jackie Kennedy as a costume. Fox, 35, explained her dress-up moment after fans criticized her look via Instagram on Friday, October 31. For a Halloween party, Fox wore a bold Jackie Kennedy-inspired look from the day John F. Kennedy was assassinated in 1963. Her outfit featured a pink tweed jacket with gold buttons and a matching skirt, which was covered with fake blood. She teamed the look with a blue scarf and matching handbag, as well as a pink cap. Fox's makeup was just as daring as her outfit, with blood splattered over her forehead and cheeks.
