I'm talking about the female imperial chain cuirass mesh. Apparrently the mod I have that modifies it doesn't overwrite the original mesh, so I can' backtrack it. Plus, I have too many mods to know which one it came from.

Probably the official Lefemm Armor plugin.

I thought this mesh was added with the Tribunal DLC?

Yeah, I think you're right.

Apparently both the Lefemm plugin and Tribunal expansion added the meshes, but only Tribunal actually assigned the bodyparts to replace the male version.
