I'm not sure if we're looking at the same thing, but that looks like it should be quilting to me. They're big, oblong shapes that don't really look 100% like scales - but artistic implications of them. You could put sparkles on top of them if you wanted to, or if you used a hologram spandex (which could be pretty) you could also quilt the big "scales" into it.
Actually in the pipes:
- Remaking Ser Loras doublet.
- Luke Skywalker, A New Hope
- Wind Waker starter costume in swim material
Eventually: Paul from Dune, Faramir, Harry Sullivan
