Continuity mistake: When Scarlett undresses for her nap after the 12 Oaks barbecue, she unties a small bustle from around her waist. She didn't have this bustle on when Mammy helped her dress for the barbecue earlier that morning.

Suggested correction: Was it under the main bustle?

Scarlett is laced up then Mammy helps her on with her dress. Looks like Scarlett is just wearing her corset (stays) with pantalets. Selznick probably adhered to the customary undergarments in the nap scene but chose no film time for the hurried scene where Gerald counts to 10 to make Scarlett hurry down to his carriage.
