Piezo-electric sustainable wedding dress?

For the ultimate in a sustainable wedding - why not wear a stylish ENERGY-GENERATING piezo-electric dress? This model is by Amanda Parkes. (Of course you could wear a solar dress as well, perhaps for the ceremony) but you could change to this for the reception. It generates energy AS YOU MOVE, so charge your removable battery with your first dance! Gives a new meaning to kinetic energy.
(and a little more romantic than this equally stylish POLLUTION-sensitive dress).
