Posting again because I didn't get to see if I got any replies in the last thread.

Any ideas on how to make Lissa's cage hoop skirt thing? Preferably collapsible, if possible

Cosplaying Lissa from FE at AN next year. Her outfit is simple enough, just wondering about two things if you guys have ideas about how to help me
1. I'll be travelling overseas to AN, so I was wondering if any of you had any ideas about how I'd make a collapsible hoop skirt?
2. I'm pretty decent with props, but I can't for the life of me figure out how to the top part of her staff. I've thought about carving expanding foam, but then I realised you need actual skill for that. Does any one have any ideas or am I just going to have to deal with not making her staff?

Much appreciated guys, pic related, Lissa's outfig

I would really love to cosplay Lissa, but I've never cosplayed or sewed before. What would be some good things to practice making/cosplaying before Lissa?
