In @SnowWhiteNews' post featuring the dolls, the first thing fans will likely notice about the new costume design for the live-action film is that Rachel Zegler's title character is wearing her traditional blue top and billowing yellow gown. However, the top is more of a jacket over another blouse in the new Snow White costume design, whereas the original top in the animated film is a one piece top.
All of the other elements of Snow White's animated costume from the original film are largely the same. The blue top compliments the character's large, white collar and Snow White's red cape, which is much larger in size than the animated film. The Snow White doll from the live-action remake also wears a red ribbon in her hair like the animated character in the original.
In short, Snow White's costume appears to match the leaked photo and video from the "Snow White" set — which Disney confirmed as authentic but unofficial photos after first insisting they were fake — where the character is standing with the seven "magical creatures" that have replaced the seven dwarves.
