Costume Analysis - Heipaoshi (modern ver)

Someone on the Guardian discord asked a question about what fabric Shen Wei's modern Heipaoshi robes were made of, and I'm incapable of shutting up about costumes and fell down a rabbithole of research, and decided to just make a big meta post. Basically a more organized version of what my research/planning process is for cosplay, lol

( Under the cut because there are a LOT of images )

I will probably do YOHE Heipaoshi at some point, though there are a lot more bits to that costume and a lot less footage of it so it probably won't be quite so detailed.
