Gone With The Wind - Scarlett's Necklace at the Barbecue
When Scarlett leaves for the part, she is not wearing a necklace. She has to run straight out to go to the barbecue, and she would not have had time to put a necklace on. When Scarlett is at Twelve Oaks, she has a red necklace on.
As the daughter-in-law of a 'Gone With the Wind' fanatic I can faithfully tell you that when this movie was finally released alot of scenes had been removed because of the length of the movie. One of them being the scene where she borrows her sisters necklace while she is napping.
