You First
I'm sure everyone has heard this by now from Brad Pitt:

"Men will be wearing skirts by next summer. That's my prediction and proclamation," he said with a laugh. "The film answers to both genders. We were going for realism and Greeks wore skirts all the time then."

I'm guessing this is unlikely, but why the hell not? Scottish guys have their kilts and a lot of the dudes in the Middle-East are essentially wearing dresses. At least in the summer they seem like they would be more comfortable and cooler than shorts.

The downside to this would be that you could no longer taunt your buddies with the "why don't you take of your skirt and ...[insert testosterone-based activity]." It would take on a slightly different meaning.
