The former wife of Rolling Stone Ronnie Wood told the Telegraph that her best friend Mairead is a vintage dress dealer, so she has plenty of opportunities to indulge her passion for historical fashion.
"We'll have a dressing up session after supper. I love trying on fabulous outfits," she commented.
Jo also told the newspaper about one of her favourite recent parties, which took place to celebrate Naomi Campbell's birthday in Cannes.
She said she wore 1970s fancy dress for the "huge bash" and spent the evening dancing to old-style disco music.
However, Jo admitted to ditching her platforms by the end of the night and boogieing barefoot like a true hippy.
Jo and Ronnie officially split in October last year following his well-publicised affair with a Russian model.
