Obviously, the strangest thing about this is that Google Glass has only been given out to those that pre-ordered at Google I/O last year, and everyone that has gotten a pair has had to sign non-disclosure agreements. We really don't want to think that Google has actually sanctioned this usage of Glass, but if not that would mean someone may have broken the NDA. Of course, the glasses in the video don't look 100% like Google Glass, and may not be the real thing, merely a knockoff.
The glasses make a couple appearances in the video. A model puts them on at the beginning, and then she walks down the runway wearing Glass and recording a video at around 2:25. Given the way it is featured in the video, it seems like Google would have to have given the okay on this, assuming the glasses in the video are actually Google Glass, which we can't confirm. But, at the very least, the models are attractive, so you can always watch with the sound off.
