I understand what you are saying Reine but I think that it is understandable that she wants to try and mimic the 'Hollywood' glamour around her. I think she will settle down and dress more conservatively when she gets it out of her system.
Of course she does not have to. She is free to dress as she wishes.
The point about the way she dresses not being appropriate for delivering an important message is interesting. She is the message in a sense.
The message is that she is a woman so obviously how she looks and dresses is part of the message. If she did not look good she would become the object of even more derision. It would make her an easier target. The fact that she looks convincing will support her argument that she is a woman in the minds of a lot of people. To go to the extreme if she presented as a male and claimed she was a woman the general public would not take it seriously. I am not saying this is right but it is the way the world is. Ask anyone who does not pass how difficult life can be.
I stress again that I know this is not the way it should be but we live in a culture where appearance is very important. It may be wrong but it is the world we all live in and as a media celebrity she is living in an heightened version of it.
