I made this HalloweenWearable to support costume wings!

It utilizes two telescoping poles and can be mounted to your back with sturdy thread. I have it mounted to a posture corrector because I found it provided the best support but the whole setup is extremely light and can be mounted to just about anything that's securely fastened to your body.

See how it works in action:
