The scarf measures 13ft or 3.96m, including tassels, and is 10" or 28cm wide.
Supposedly knitted for the Doctor by "witty little knitter" Madame Nostradamus, the scarf actually began life when Begonia Pope received the commission from costume designer James Acheson. Acheson had been inspired by Henri de Toulouse Lautrec's painting of his black coat and long scarf-wearing friend Aristide Bruant, and bought a mass of multi-coloured wool. Pope proceeded to use it all and the cast and crew fell in love with the idea of the Doctor having an absurdly long scarf.
Maninder Singh Sahota, Director of Lovarzi, says:
We feel proud to be working with the BBC to create such a wonderful product. We've worked hard to deliver the best-ever Doctor Who scarf; we're sure Doctor Who fans will absolutely love to own one.
The scarf, priced £49.99, is available from retailers including Amazon UK.
