The Doctor's Fez As Worn By: Matt Smith on "Doctor Who" A fez had popped up on a couple of previous Doctors (namely Sylvester McCoy and Paul McGann), but it was Matt Smith's 11th Doctor who was especially fond of the red fuzzy hat, insisting to River Song that "fezzes are cool," a defense he also used for his beloved bow ties. Sadly, River Song and Amy Pond did not agree, and they destroyed his fez the first chance they got.
