It looks like in the AU version of the play Anastasia gets to wear her blue dress longer on stage!
The preview for the Australian performance of Anastasia the Musical seems to suggest Anya will still be wearing her blue opera dress while speaking to her grandmother when she's finally recognized.
In the American performance of the play, she has already changed into another costume by this scene.
This change of keeping her in the blue dress longer is actually more faithful to the original animated film!
