Check out Bonanza. Lorne Green never changed clothes once.
Coincidence but just this morning I read a piece about filming Bonanza. The cast basically never changed clothes for the 14 years that the show ran. Exceptions as noted for a wedding etc. that called for different clothes. It stamped the character ID almost like a superhero costume, and it saved quite a bit of money in the costuming.
Read one time that Clint Eastwood had a ratty old serape and hat when he went to Italy to film the Good, Bad & Ugly movies. The Italians had no western cowboy type clothes so his own stuff became the costume for the whole series.
