Elsa’s dress from Frozen is the sort of costume that begs to be enhanced with electronics. Redditor gingersnapss used blue fiber optics in her take on the dress and made everything from the gown, to the shoes, to the beads, sparkle. Since she sewed the costume from scratch, it was easy for her to build in the light-up effects. She handled all the details like dyeing the fabric on a blue gradient scale and adding all the beads and rhinestones and hand — I can’t imagine how long it took to do that.

Bonus: She used YouTube videos and Adafruit to learn. She says:

Thank-you! I basically was just curious about how could I make this dress stand out from all the other “elsa’s” what could I do to make it really fun? I was browsing the internet for ideas and came across a Jelly fish dress http://www.instructables.com/id/Fiber-Optic-Dress/ I loved it! I used basically the same method she did. Only now Ive learned a bit more about LED’s and wish I went a different route. I learned almost everything from youtube and Adafruit.com 🙂 I suggest looking around there site and forums really useful stuff!

She’s been working on the costume for about three years and experimented using different bodices and skirts and everything. You can see more photos below.
