The costumes
I consider this film to be a cut above 'Gone With The Wind,' mainly because there are some very realistic touches about the brutality of war.
However, the one jarring aspect of the production that makes me cringe is Nicole Kidman's wardrobe. She truly is dressed to look her best, not to look authentic for that period in history. Everyone else in the cast dresses appropriately.
The scene at the end of the movie - would a woman of that era wear stylish black that showed her form? I don't think so. Rene Zellweger wearing pants is a whole other story: they are baggy, she is layered with clothing and so she seems almost shapeless. I think that's probably the way a woman of that time would have dressed if she work trousers.
