Phantom of the opera Christine Daae is supposed to be a figure of innocence throughout the film and as such her dresses reflect this. This dress is fitted and sophisticated but is white and therefore a colour connected with being virtuous. I love the cut and draped skirt on this dress especially in the way it reflect the ripples in the water.
When the Phantom sees that Christine is falling in love with Raoul, he writes to her saying you need to listen to me and do what I say or bad things will happen. He does this many times within the novel. Phantom wants Christine all to himself and this results in jealousy that leads to many feuds. Like the quote states, if she does not listen to him, he will curse every day to follow.
