Once we learned that Coco Rocha lends her modeling expertise to agencies and new faces, teaching them the tricks of the posing trade, we naturally invited her to give us a private tutorial. When she arrived, our standard office setting suddenly came alive with the potential for major fashion moments. Not only did we learn how to get fierce in a bathroom stall, but also how to emote while doing it. (Hint: Reciting your vowels will contort your face to express various emotions). There was a walk-off with a mail cart — the key to killing it here is to only push it with one hand, while sexily mussing your hair with the other — and a rapid-fire round of poses in the elevator, changing it up with each floor. Check out the clip to pick up a few tips of your own, and also to marvel at how entertaining Coco is on camera (someone needs to give this girl a guest-judge spot on one of those fashion reality shows, already, at the very least).
