The two sets of shirts and pants, and the robe from gnomey's concepts is a good intial set, but more concepts and variations welcome. Feivelyn has provided additonal concepts, please make these as well.
After posting some images of my latest project shinanigans, involving hooded recolours of a few vanilla robes, I was suggested to provide these assets to TR, so here I am showing my current progress. the most developed hooded robes are the "Expensive_03" robe variety, with a few early concepts of a few other robes, and still very conceptual "pyromancer" robes, which with work, may or may not be suitable for chameleon 'ghost' NPCS.
