Tuxedo
From Tardis Wiki, the free Doctor Who reference
The Tuxedo was a type of clothing from Earth, generally worn on special occasions. The Doctor had a tuxedo which he sometimes wore. He believed it was cursed, as life-and-death situations occurred when he wore it. (DW: Voyage of the Damned)
The Tenth Doctor wore his tuxedo at Jackie Tyler's birthday, (DW: Rise of the Cybermen/The Age of Steel) the press conference at Lazarus Laboratories (DW: The Lazarus Experiment) and on the Titanic (DW: Voyage of the Damned).
