Imagine if you are a princess, as a political asset for your own race, you will have to appeal and best your competitor in many aspect. It doesn't matter how 'you' would like to approach it, but in a situation of political marriage, results matter. I would do a salve Leia outfit if that's what it takes to win my race a strong ally with a freaking jetpack mounting dragon. I'll do magical plastic surgery to make me appeal more to human even if I'm a (half) lizard woman.

So quit bitching about those minor details and focus on the story and gameplay.
