Bow tie

A bow tie was a type of men's necktie in the shape of a bow. They could be either pre-tied or self-tied. The Doctor wore a bow tie in both his second and eleventh incarnations.

The Second Doctor's bow tie appeared along with his other clothes when his first body regenerated with the TARDIS' assistance. As with the rest of his clothing, the Second Doctor's bow tie was untidy and crumpled.

The Eleventh Doctor adopted a bow tie along with the other clothes he stole from Royal Leadworth Hospital soon after his regeneration. (TV: The Eleventh Hour). He would often insist that "bow ties are cool" in spite of his companions' disagreement. (TV: The Eleventh Hour, Vincent and the Doctor, The Lodger, A Christmas Carol, et al.) During his period of retirement after losing Amy Pond and Rory Williams, the Eleventh Doctor changed his outfit to something more befitting his sojourn in Victorian London, but put on a bow-tie again when spurred back into adventure by Clara Oswald.
