Regarding hair style, you've done nothing but demonstrate your own lack of understanding of the female gender. Many women change how they wear their hair, quite frequently. It should be no surprise that a woman in the public limelight is even moreso inclined to vary her style over time. The image on the right that you are referring to is *years* out-of-date. Besides that, you must understand that the Princess is in captivity; she doesn't have the luxury of doing her hair to the degree that she did during the carefully staged photo-shoot that you are comparing it to.
As to her facial features, your analysis is too simplistic. It is in fact difficult to compare two faces that are at different angles. Your results here are inconclusive.
Regarding skin color difference, the reason should be obvious: different lighting conditions. Do you not realize that the color we perceive when looking at an object is a combination of both the object's optical characteristics, as well as the light illuminating the object? My cargo area is relatively dark, and is illuminated by some relatively dim white lights, as well as some blue lights. In contrast with your photo, the Princess ws clearly in a very brightly lit environment. We should naturually expect her skin color to appear darker in the darker environment.
And last but not least, her chest measurements. The fact is that the "official" photo of the Princess has intentionally been "un-enhanced" by imperial propagandists. They felt that the princess's true appearance would draw too much attention away from her important political message, so they doctored the official photos. Personally, I would have taken her message much *more* seriously had I known her true measurements.
