In my opinion this will be the real application for "Wearable" technology. The technology going into the dress material that can chnage the color, shade depending upon the ambient light and the mood of the wearer , can become warm or cold depending upon the outside temperature, can generate the desired scent without the need to apply perfume and so on.
So the Haute Couture has now new challenges to its creativity!
Got to love this human body symbiosis...when you think about it it is amazing that high-tech has never tried to invade fashion...but we have got all the gadgets and technology to do so! (slick covers for smart phones don't count here)
