Amanda Knox wears her old 'prison uniform' while preparing for upcoming wedding

Amanda Knox has a rather unique way of preparing for her upcoming nuptials: wearing her old "prison uniform".

In an Instagram post shared on Sunday - the 32-year-old who was was wrongfully convicted for the the murder of Meredith Kercher in Perugia, in 2009, and was later exonerated in 2015 - can be seen wearing a sweatshirt and sweatpants, which she reportedly wore while imprisoned in the Italian city.

"40 days left until the wedding and 267 tasks left on the wedding To Do list. I've locked myself in the craftroom and I'm wearing my old prison uniform," she captioned the post. "Literally the very same sweatshirt and sweatpants I lived in in Casa Circondariale Capanne, Perugia."

Knox and her fiancé, Christopher Robinson, created a website this past summer where they asked for donations to help crowd-fund their space-themed wedding.

"Let’s face it, we don’t need any more stuff. What we do need is help putting on the best party ever for our family and friends!" the couple wrote in the registry section of the site.

"Instead of a traditional registry, we are asking for donations towards the cost of the wedding,” they continued. "Whether you’re attending or not, all are welcome to donate to specific costs, or at a patron level." They also detail that everyone who donates will receive a signed, limited edition of The Cardio Tesseract - the pair's book of love poetry.

Knox was an American student studying abroad in Perugia in 2007 when she was accused of murdering her roommate, 21-year-old Kercher, who was found with her throat slashed in her bedroom.

Knox, who was 20-years-old at the time, was convicted for the murder alongside her then boyfriend, Raffaele Sollecito. Prosecutors claimed that Kercher had died during a sex game gone wrong, despite minimal evidence implicating the couple.

In 2011, the pair were freed after four years in prison after being acquitted by an appeals court. However, they were again convicted in absentia in 2013, before being exonerated once more in 2015.
