Summary
Concept art of stillsuit headgear variations (cowl and nostril plugs) for Dune (2021), by Joseph Cross.

Joseph's commentary: "I had the privilege of working on the Dune in early production and contributed to a number of costumes and props working with Denis Villeneuve and Patrice Vermette. This first of which was the Stillsuit which started pretty broad and narrowed quickly. A lot of talented folks ended up contributing and I am grateful to have been part of it."
