I also wanted to light-up the tulle layers on the skirt with static lights. Because sometimes I may want to turn off the heart-rate-monitored LEDs so they don't constantly flash people but do want to keep some parts of the dress lit up.
For this, I used conductive tapes stuck on tulles and connected the tapes with the LEDs using conductive threads. This makes really nice soft circuits as the tapes are flexible and sticking them is much faster than sewing conductive threads.
I sewed the entire piece in between many layers of tulles to create a diffusion.
Finally, the beautiful flower decorations and the zipper!
