Tuxedo
From Tardis Wiki, the free Doctor Who reference
The Tenth Doctor wore a tuxedo in the episodes DW: The Lazarus Experiment and DW: Voyage of the Damned. Also, in Voyage of the Damned, he commented that the tux was really unlucky. Later, the Eleventh Doctor wore a tux to Amelia Pond and Rory Williams's wedding in DW: The Big Bang.
