Let me fill you all in on something: any material that is shiny in any way will put any flaws you may have on display. Pants like this work almost like a spotlight for things you don't want seen. It also makes legs appear larger--that's just how shiny material is. And that's why we should all avoid it unless we have model-esque bodies (and even then, the look is debatable).
I aslo have a problem with the high waist. When will this trend be over? High-waisted pants simply makve everyone's mid-section look huge. For a flattering look, you want something that cuts it in half to diminish this.
Even the model doesn't look great in these pants. That's a pretty good indication that no one should be wearing them. Ever.
