the armor is a mixture of several pieces and mods:
pants - clothiers of vvardenfell
shirt - looks like a work of oni-k. could be from etoffé guerrieres. i know it, but i'm not sure from where
right pauldron - looks like one of westlys mephala gear from shine of mephala
left pauldron - could be a daedric one but from either westlys arcane dremora armor from markyna gatanaz or from cenobites sixy daedric armor
the gauntlets i'm not sure about. looks like chain mail
the sword i don't know.
Shirt is from Heaven's Lookout.
Right-pauldron is from one of sinblood's works. A Drow armor, can't remember the specific name.
Left is an ordinator retexture mishmosh, from either the Armamentarium, or the Night Gallery, or possibly one of Qarl's Gothic Attires. If not the exact one, there are multiples that would be close in any of those, I'm sure.
Gauntlets are part of the Malefice [The name is close, but likely not exact] armor, but I cannot remember what mod they are from. I can tell you that I buy the armor in Suran from a dancing lady in the House of Earthly Delights. [As I look over my modlist, it
might be 'Exotic Imports', by Westly.]
Sword is from 'The Hidden Pathway' mod.
Sorry I can't be more exact. My game has been the same setup for several years, other than the occasional tweak. I'm surprised I remember this much. XD
