Anastasia (1997, Meg Ryan, John Cusack)

When Anya is out of the adopter's house, during the song and afterwards, there is a massive amount of snow coming down, though none of it is stacked on her cloth or head.

When Dimitri gives Anya the blue dress, it's got these white ruffle-thingies at the bottom. When she puts it on and appears before Vlad & Dimitri, the ruffles disappear.
