Black Ruffled Dress with RGB LEDs
The skirt of this dress is decorated with about 60 RGB LED pixels that are programmed to display a variety of colors.
The pixels are mounted on an inner layer of the skirt, and the light is diffused by an outer layer of sheer ruffles. A similar effect can be achieved by mounting the lights on an inner slip that is detachable, to allow it to be transferred to another dress, and/or to give you more laundering options.
