Costume Critique #4 -- Stardust

Stardust is my movie for this week because Ingrid recommended this to me. Costume designing is done by Sammy Sheldon, who also has done costuming for some other movies such as The Immitation Game in 2014.
Time period is about 1800's in England. A magical kingdom is hidden from the other English villegers until a English boy Tristan adventures and becomes a king in the kingdom.
I did not understand about Yvaine's costume at first because the fabric used for her dress when she fell from the sky (she used to be a star up there) was very different from any other characters, and it made me feel a little weird. I felt her dress was too shiny that does not really match with the other characters' costume. However, when I watched a costume designer explaining how she cameup with the idea of Ynaine's dress and how she wanted Ynaine's dress to give impression of shining star, I get the reason of using shiny fabric for Yvaine's dress.
I liked the timing of costume change for Yvaine and Tristan.

Yvain's first costume was like an alien taste, and Tristan's was like a poor village boy who wears what his father used to wear. As they continue their adventure, they changed to more retailed outfit, which, I think, represents the change of their mind. Yvaine started to like Tristan and to decide that she would be a human as Tristan is to stay with him. Tristan was not confident person at first, but he became more manly and strong enough to protect a lady.
