Put on, as a costume (3)

Ross

I believe the answer is:

don

(Other definitions for don that I've seen before include "A Spanish grandee like Quixote" , "Member of university" , "Spanish gent or Mafia chief" , "A Mafia chief like Corleone" , "Spaniard in a University?" .)

I've seen this clue in The Washington Post.
