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. ("The Eleventh Hour", "Vincent and the Doctor" "The Lodger", "A Christmas Carol" et al)
