Kate Hartman and Rob Faludi co-developed LilyPad XBee, a LilyPad Arduino Main Board addition that enables wireless communication. Now you can add even more functionality to your garments by allowing them to communicate to each other.
According to Sparkfun, the "LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!" Like the LilyPad, the module is designed so that it can be sewn directly into fabrics and there are a variety of different modules with different specs. I can't wait to get my hands on them!
