I didn't see anywhere in the article where it said his pants were baggy. I'm assuming he was probably wearing saggy skinny jeans. This seems to be the new trend, which I think is even worse than baggy jeans. At least baggy jeans sag because you know, they're too big and you need a belt, but what's the saggy skinny jean all about?
I'm frankly more offended when people go on flights wearing what I consider to be pajamas.
