When she had the Count brought to the Italian Villa, she's in her dusty uniform. Then she cuts her hair and appears in a dress...and in a later scene, a different, print dress. She couldn't have found these perfectly fitting clothes in the villa! And she couldn't have been packing them, because we didn't see her with any kind of pack. Just a bit of Hollywood costume magic?
shareProbably from the movie convention that when a character needs particular clothing in an out-of-the-way place, they will find it, and it will always fit perfectly and look appropriate. -Especially if they have to get it by stealing it.
Another great example: "55 Days In Peking" where David Niven and Charlton Heston make a raid on the Boxers that are besieging the Legations, in captured Boxer uniforms - which, true to the convention, fit perfectly. Niven was 6', Heston was 6' 3". I wonder, how many dead Boxers did they have to sort through to find those?
Just watched the film again, and noticed she had 3 outfits. I think Caravaggio stole the blue one for her. It shows up after he does.
