The freckles on Anne's face change position, colour and size between shots in every episode.
The freckles on Anne's nose are arranged in an artificially uniform pattern that does not occur in natural freckles.
Multiple scenes depicting Anne from behind show clearly that her pinafore and her dress are a single piece, with the buttons from her dress continuing onto the pinafore. In this time period, the pinafore was a separate piece worn over the dress to keep it clean. It was never attached to the dress so it could be easily changed when soiled.
