/cgl/ - Cosplay & EGL

So, I'm cosplaying Mako from Kill la Kill and I'm struggling on how to make the coat look like hers. I want it to "float" like hers, any idea what could I use?

I thought about putting some wire at the edges but the coat is quite heavy and long but I'm not sure if the wiring would be enough to support it.

Should I make some kind of wire structure instead of just passing wire at the edges? I'm scared the structure would be visible, like a crinoline can be seen under a skirt.

Left - what I was going to do but I'm now afraid it won't work.
Right - An idea on how it could work.

Could anyone that ever worked with wire shine some light on it?
