I'm working on this costume for myself, I'm printing the armor parts in PLA and I want to cover them with fabric just like I saw in the photos of the official costume, do you have any idea what fabric to use for?
It looks like some sort of ballistic nylon like you’d see in tactical gear, I’m not sure if it’s elastic at all though. I say take a trip to a local fabric shop and see/feel what you like for yourself, nothing online will be as good as that.
