I know I'm posting this a little late in the game, but I just registered.
I don't see anything wrong with Georgie...Someone, I forget who, said she looked dumpy, but she was wearing a heavy winter coat (yeah, I know that was said several times), and also she was smiling. Smiling pushes your cheeks up a little bit, making them look fatter than they really are.
Judy Garland WAS attractive...but she didn't fit that time period's picture of beauty. She was shorter than girls like Lana Turner and such, she wasn't "busty", and she was type-cast in "little girl" parts well into her teens. Louis B. Mayer, one of the founders of MGM, actually called her "little hunchback" because she had mild curvature of the spine, and she had a dental piece to wear for movies because her teeth were a bit crooked. Her life began its path to self-distruction because people were telling her how thin she had to be, because she was popping uppers during the day and downers during the night to keep on a schedule, and because in spite of all this it still wasn't enough to satisfy the people who asked this of her. So, personally, I don't think we should be worrying so much about how a child star looks, so much as how well they can act.
