Tenth Doctor's brown suit

The Tenth Doctor wore a dark brown suit with blue pinstripes as part of the costume he chose in the TARDIS wardrobe following his regeneration from the Ninth Doctor. (TV: The Christmas Invasion) Following his travels with Rose Tyler, the Doctor alternatively wore a blue suit with red pinstripes. (TV: Smith and Jones)

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)

The Doctor was wearing the brown suit when he regenerated into the Eleventh Doctor. (TV: The End of Time) Shortly after, the Doctor removed his jacket as he moved to take control of the damaged TARDIS only for it to crash land in Leadworth in 1996, with the ordeal inflicting damage to the suit. Eventually, after returning to Leadworth in 2008, the Doctor, in full view of Amy Pond and Rory Williams, swapped the attire of his previous incarnation for clothing which he stole at the Royal Hope Hospital; Rory chose to look away as the Doctor undressed, whilst Amy watched intently. (TV: The Eleventh Hour)

The Fourteenth Doctor, who bore a curious resemblance to the Tenth Doctor, emerged from his regeneration wearing a similar brown suit. (TV: The Power of the Doctor)
