There isn't a youtube video. It only lights up.
The dress (Hi, it's the girlfriend talking here)
First, I began with fabrics that fitted the requirements-sheer and reactive to UV lights. Despite many white fabric variations, some reflected brighter than others. The sheer fabric I ended up using is called, Organza. I ended up going through many dress prototypes, and I resulted in the bodice that you see, and the skirt with 16 panels, shaped to give the skirt structure. Within each skirt panel seam, I did a specialty seam that would allow them to lay flat, and I striped plastic boning pieces thinner, and inserted them within the enclosed seams. I also finished the hem with boning to make the skirt span out. With the flowers, I made each of them by hand, burning the edges with a lighter so that they would curve out and resemble a rose. There are about 45 handcrafted flowers. Keep in mind, as an apparel major, it almost took me a month to make this dress - and organza is very hard to work with- so if you want to make something similar, you might want to contact an apparel major.
Hey its me again(the engineer)
Mainly the only issues that I encountered was the wire. A 22 gauge wire was much too thin and broke all the time, not to mention while soldering the joint, the wire became extremely hot even though it had insulation. To fix that, I salvaged some of my breadboard prototyping wires and now those are in the dress. Defiantly keeping them organized was difficult since we couldn't use any colored wire since it would stand out. To fix that, we used nail polish since a sharpie didn't stay on the insulation of the wire. If you get past all of that, you will need to find some way of keeping the clump of wires together, so you just twist them together.
Organization: the way the dress was wired was we brought all the anodes together on one side, soldered them all together and then soldered another wire that would represent those anodes on that side. We did that with all the cathodes as well as all the others on the other side of the dress. After we had those we, connected both anode representation wires together and then the two cathode representation wires together and had an extra wire hanging off of each one, the two extra wires(one from the anode and one from the cathode) were then connected to a JST socket. We then had the battery have a JST connector. This is how we kept it organized.
Another tip is to have a piece of hard paper or something that you can put between the dress and the solder joint. Keeps the solder from sticking to the dress if it falls.
So there ya go, that is how we made the dress
