Tom Baker's long scarf was created by accident
According to legend, James Acheson, the series' costume designer, is supposed to have provided several balls of yarn for a knitter to choose from while making a normal-sized scarf for the Doctor. Instead, she knitted the lot into one single, gigantic item, which Acheson, displaying the keen eye that would later win him three Oscars for costume design, decided to keep. It became an instant hit. 'The crew sometimes used to stand on it and yell with laughter when I spun around,' Baker later explained.
