You know what’s truly sickening about this particular scene? This dress (before the mice gave it a makeover) originally belonged to her deceased mother. Cinderella hardly has any personal possessions due to the greed of her stepmother and stepsisters. So, I assume that this dress meant quite a lot to her as a reminder of a simpler and happier time in her life. It symbolizes a fresh start and a chance at a better life for her. It must have been traumatizing to see her dreams just destroyed, literally ripped from her, torn to shreds. Not to mention, they verbally abuse her calling her a “thief” and a “kitchen wench”. In the end when Cinderella is standing alone in rags, it’s animated so beautifully because you can feel this weight and this sense of hopelessness. Cinderella’s a girl who even said herself that no one could take away her dreams. But in this scene, you can see she’s giving up.
That’s why it is so important that Cinderella gets her happily ever after. Her Fairy Godmother is a symbol of faith and perseverance in hard times. After all, “Even miracles take a little time.”
