Indeed it could be a lil bit weathered. At least the references show some. The promo pic for example shows clean clothes. I‘m afraid to not get the exact weathering on this kind of fabric and to mess it up. So it will stay without weathering.
I got new pics from „AK Fotografie“ today. I really like them.
Even just a little Fuller's Earth in the recesses would do a lot to add dimension to the costume, and you can always wash it off. And I don't think you need to get any weathering exact on a costume, it's not a V2 stencil type situation, really.
But I'll shut up about the weathering! Still, so very cool, love it!
