This is probably my favorite costume I have ever made! The character is based off Ahri from league of legends, a nine tailed fox.
I made the entire 9 tail harness and led light orb. The tails are about 5 feet long each. I made a wooden harness for my back and ran 9 gage wire through them and secured with bolts and washers. I patterned the tails myself and cut them out of fur, then sewed them closed, and secured to my harness!
The orb that lights up is made from clear acrylic, I sanded down and set up the LED lights on the inside to give it some awesome glowing effects!
