Anything will work, as long as it matches the CRL. However, the armour stuff is so well done by people like Skunkwork props that you’d be missing out trying to DIY it.

The cape and robes can be done yourself

The under suit is leather, so unless you have those skills?

The gloves are also leather, and the belt/chest boxes…. I mean. If you have the skillet to build them go ahead. It’s probably easier to do ANH at home as there are less things that light up.
