One of television’s most persistent costume myths — the origin of the Fourth Doctor’s insanely long striped scarf — comes straight from the man who designed the show’s costumes. In the early 1970s, while working at the BBC on Doctor Who during the eras of the Third and Fourth Doctors (Acheson handled dozens of serials from The Mutants and The Time Monster through The Deadly Assassin), James Acheson sketched a look for incoming lead Tom Baker that drew on eccentric period posters (Acheson himself cited a Toulouse-Lautrec poster as a visual touchstone). He purchased an ample supply of wool intending to give the Doctor a somewhat rumpled, bohemian accessory. A close friend agreed to knit the scarf as a favor — and, according to Acheson’s own telling, used every last bit of the wool. The result was the unintentionally gargantuan scarf that quickly became the character’s signature.
The story reframed what might have been dismissed as a prop fluke into a deliberate and iconic design choice. Acheson’s role on the production extended beyond that single piece — he was responsible for creating the first colour-television versions of the First and Second Doctors’ outfits and for monster and costume construction across many serials, often working with materials such as fibreglass, latex rubber and molded plastics. The “too-long scarf” anecdote settled into pop-culture lore as an origin story that is verifiable (Acheson has recounted it himself) rather than pure urban legend, and the accessory’s accidental excess helped define Tom Baker’s screen persona, drove merchandising and fan cosplay for decades, and stands as a neat example of how a small production quirk can calcify into an enduring television mythos.
