Looking at the close-ups of her face, I'm quite positive that you're right! Back in FW 12 her eyes were hazel-ish and now they are blue, and in a bunch of the shots from stylebistro you can see the slightly dotted pattern of the blue over bits of her pupil, and the more yellowish ring of her natural eye color on the very inside of the contact and surrounding the pupil. I love the contacts though; they make her stand out a bit more to me and her eyes kind of remind me of Daria Strokous's eyes now
Anyways yeah, she's superb, especially at Helmut Lang. Best of luck in Europe!
