About 20 mins into the movie, when Dorothy Lamour is talking to Henry Fonda from the steps of her wagon while wearing a robe, how she wears the robe changes from shot to shot. From the side view she has it discretely wrapped around her. From the font view she has it pulled tight and slightly open all the way to the waist, and is not wearing anything underneath it. In the final front view as Linda Darnell enters the scene, she has it very loosely wrapped and is wearing a slip underneath it.
