I LOVE LOVE LOVE LOVE LOVE Aurora's! Her blouse is off the shoulder just like in the movie! I really wish Disney would get away from those awful, misshapen, loss fitting, one size fits all costumes they put those girls in. The princess should be good role models and show all those girls just how to work an off the shoulder gown!
What's interesting is that they went with a completely different color on Aurora that isn't even close to what she wears in the film. The style is very similar.
While I can see that Disney would like to be able to have a CM change makeup, dress,and wig if need be, it's more challenging with Aurora because she's taller than the other princesses. With Eyvind Earle's very vertical and angular background design of the film Sleeping Beauty, they had to make the characters fit the background, so Aurora became very tall and slender. You'll notice that both her peasant dress and princess gown in the film are more streamlined than the other princess dresses. All of them have some degree of poofiness to it, where Aurora's have none.
I wonder if they've gone to making the upswing of the blouse stand straight up (as well as made her crown taller) in an effort to make her appear taller.
To me purple is a compromise between the pink and the blue. I actually like it better than the pink because my overactive imagination has decided it's right in the middle of the duel over the color.
And the dress does appear purple for a total of one scene in the movie, which I only discovered after making some avatars for another site. You basically have to watch the first color change sequence when they're making the dress frame by frame to catch it.
