Seventh Doctor's jumper
The Seventh Doctor wore a jumper covered in question marks as part of the costume he chose shortly following his regeneration. This attire was approved by the Rani, then disguised as Melanie Bush. (TV: Time and the Rani) By the Doctor's own admission, the jumper was "silly". (AUDIO: Harvest of the Sycorax)
Following the Thirteenth Doctor's forced regeneration, the jumper was among the items of clothing worn by the Spy Master during his brief stint as "the Doctor". (TV: The Power of the Doctor)
Petronella Osgood or her first Zygon double wore a replica of the jumper whilst recording their message regarding Operation Double. (TV: The Zygon Invasion) It was later worn by Bonnie after becoming Osgood's second double. (TV: The Zygon Inversion)
