Bow tie
From Tardis Wiki, the free Doctor Who reference
Bow tie were a type men's necktie in the shape of a bow. They could be either pre-tied or self-tied. The Doctor's Eleventh incarnation would often insist that "bowties are cool"in spite of disagreement on the part of his companions. (DW: The Eleventh Hour, Vincent and the Doctor, The Lodger, A Christmas Carol" et al)
