Tenth Doctor's blue suit

Following his travels with Rose Tyler, the Tenth Doctor wore a blue suit with notched collars on the blazer and red pinstripes (TV: Smith and Jones) as an alternative to the initial brown suit he selected in the TARDIS wardrobe following his regeneration from the Ninth Doctor. (TV: The Christmas Invasion)

Travelling through the caves of the Death Zone to save Borusa from the Dark Tower, the War Doctor and Cinder found various cave paintings that depicted the Doctor throughout his life; the War Doctor noticed one of "a lanky man in a blue suit", and recognised it as one of his future incarnations. (PROSE: Engines of War)

Clive Finch, who had assembled photographic records of numerous incarnations of the Doctor by the time of the 5 March 2005 incident, was aware of one Doctor with two suits, brown and blue. (PROSE: Rose)
