/cgl/ - Cosplay & EGL

So I'm planning on making Eliza in the upcoming future, but I'm stuck on her ankh shawl thing. I was thinking of craft foam to keep its shape, but I don't know if that'll work well to keep it upright and not droop much. Also, is there a good way to keep it centered or attatched since it's only in the front? It's my first time really trying anything like this, so I'm a little lost.

What would be a good way to do it? I've been looking around and searching and haven't seen much besides the craft foam, but I was curious if there's other ways. I'm on mobile so my apologies if the picture ends up sideways.
