Because I don't think that outfit emphesize her beauty in the right way. I don't think these kind of pants are good for her, and the worst part is that belt.
But its a question of personal taste.
I would much more like something in the lines of DBS video, just the top being long sleeved, for example. Its more classy and suits her better in my eyes.
But well, she wears it and not me.
