*Okay, it's fashion design-fiction. But you know what's great about this? This electronic clothes designer has enough common sense to hire an actual model. And a real fashion photographer. That's what makes it good design fiction – as opposed to say, a FlickR snapshot of an Art Center grad grinning over her hotwired Arduino board.

"Communicate to your friends
"Technology is integrated into the mechanics of the garment. For example, a sensor is entegrated into the hood allowing the natural gesture of lifting the hood and putting it back down to communicate to Facebook. Lifting up the hood automatically sends a message and updates your status. Putting the hood down sends another message. A Facebook application allows you to customize your messages, assign them to groups of friends and even manage many different types of messages based on where you are, who you're pinging, or what your mood is.
"Get a ping back
"Technology is integrated into the shoulder of the garment that provides a subtle "tapping" feeling. If your friends send you a comment or a message back, the garment will notify you by tapping you on the shoulder...."

*That was a good choice of shoes, too.
