My thighs were huge; they were like rock! Growing up, I was really athletic, and I had a very athletic body.

I usually do my hair and makeup in 30 to 45 minutes, and if my hair is dirty, I'll just put it in a bun or a ponytail. If it's in a bun, I'll part it down the middle and do a low bun with a couple pieces in the front coming down.

My Pirelli calendar is hanging on the wall of my friend's frat house, and he doesn't know anything about fashion. That balance is what leads to big campaigns outside of fashion. But I never want to choose one or the other. Both commercial and high fashion are what make my job so interesting.

I will be the first to say, when I started, I was the worst on the runway ever. I feel like I try to keep learning every time I step off a runway; I try to get better with each one. I hope that I'm getting better as I go - it takes a few seasons to get your Karlie Kloss walk on.

Social media for the majority of companies is not about helping customers or improving products.

As the world becomes a more digital place, we cannot forget about the human connection.

The important thing about mobile is, everybody has a computer in their pocket. The implications of so many people connected to the Internet all the time from the standpoint of education is incredible.
