"Doll" is a name that some people call women in general or a lover who is a woman. Using "doll" in this way in general is not common, but it is somewhat more common in the southern part of the United States. He uses "doll" here because they are dressed like people from the 1920s, and "doll" is an old-fashioned term from that time.
