Kate’s childhood friend, Thomas Waley-Cohen, whom the ward was named after, had tragically passed away from bone cancer in 2004 at just 20-years-old.
Royal fans have taken to social media over the years to comment on the now Duchess’ past bold look.
@kr_mccroy wrote on Instagram: “She was just a child here and not yet married to William.”
Another user, @prprinsessa, coined it a “perfect Halloween look”.
