One of our favorite Western movies for historical accuracy though..

… is the 1993 “Tombstone” with Kurt Russel.  Not only are the character depictions spot on (wives are sedate in homemade goods, while the rich actress is in high fashion silks with copious trims), but they even have the undergarments fitted as the characters would.  The “regular women” wear “every day clothes” with some fitted better than others, while the “high fashion women” are flawless in design and accurate detail.
