Its really common when it comes to movie & entertainment costuming to more or less “adapt” period clothing using more contemporary cuts/textiles/colors etc. as both a tool to relate better to modern audiences and so they don’t look “too weird”.

Every time a period piece comes out historical costuming spaces implode with debate about historical accuracy with people coming from both “it should be as historically accurate as possible otherwise the movie is a sloppy terrible mess” and “historical accuracy is important, but costume designers often pair accuracy with deliberate anachronistic choices to accentuate the story and a character’s personality”.

Good times.
