Infineon Technologies have just launched a Wearable Electronics range. Controls are fed through to touch pads on the jacket sleeve (or hidden in a pocket flap), and a wiring loom routes control and audio. As well as the "hip" clothing examples they also show normal business suits and work uniforms (eg nurses).
The first commercial item being O'Nellls The Hub snowboard jacket, MP3 player and Bluetooth hub. No idea of cost yet!
