9. Cinderella (1950)
In the 1950 classic Cinderella, the happy bride is seen riding off into the sunset with her prince in a golden carriage.
In one shot, the new princess has long sleeves on her gown, completely covering her arms. In the next shot, the sleeves have miraculously shortened to cover only her shoulders.
Cinderella is not the only Disney Princess on this list; slide 5 has a great princess blunder too.
