Sara's Trousers - Where To Find?

Today it's Germany's Next Topmodel's night and I wanted to show you the lovely oufit from Sara (left one). Her trousers were absolutly awesome: elegant and comfy at the same time. Where can I get those?
Unfortunately I only found this picture, but hopefully you can guess what I mean.
