The Revan/Star Forge outfit is usually controlled by these files:
PMBJS.mdl / PMBJS.mdx
PMBJL.mdl / PMBJL.mdx
PMBJM.mdl / PMBJM.mdx
PFBJS.mdl / PFBJS.mdx
PFBJL.mdl / PFBJL.mdx
PFBJM.mdl / PFBJM.mdx
Unless the appearance.2da file is changed to a new model name. Try deleting those files along with any TGA files associated with them (pmbj01.tga, pmbj02.tga, pfbj01.tga, pfbj02.tga etc).
Let me know if that works
