I doubt I have all of the folders, but I'll list the ones I've got.
Nexon\Vindictus\en-US\data\materials\models\player\nudemod
" \ " \ " \ " \models\armor\<ArmorName> *

There are dozens of armor names and four character names. When I typed "<CharacterName>" up above, I'm referring to the names of the classes. Evie is Evy; Lann, Lethita; Fiona, Fiona; Karok, Kalok.
As for armor names, there are dozens:
adventurer,
battlemail,
beginner_cloth,
blackhammer,
blackhammer2,
bloodlord,
bloodsilk,
blossom,
brokenash,
crimsonrage,
crystal,
deathclaw,
dorothy,
fallenrock,
formal,
fungus,
ivyplate,
kobold,
lab,
lagho,
lightplate,
midnight,
natural,
newbiewear,
nightmare,
northern,
premium_youth,
prince,
queens_lust,
redbear,
reinforce,
rosedrop,
savage,
scarlet,
sharpshooter,
shiningwill,
southern,
spidercloth,
spiderlord,
standalone,
standalone2,
studded,
stuffy,
sweety_bear,
swordwind,
swordwind_tunic,
temp_stocking,
tempationer,
veteran_raiment,
waredge_battlesuit,
wbs,
wild_duke,
and wingplate.
The armor and character names are folders on their own. My armor files are models for broken armor. Not undamaged armor. The files are all called "pc_female_<ArmorName>_<ArmorPiece>_broken." An example file name would be "pc_female_bloodsilk_upper_body_broken.dx80.vt x." There are five file types for each file name. These are:
.dx80.vtx,
.dx90.vtx,
.mdl,
.sw.vtx,
and .vvd.
Another example would be "pc_female_bloodsilk_upper_body_broken.sw.vtx" or "pc_female_bloodsilk_upper_body_broken.mdl."
Now, going back to the paths I posted and the character name folders I mentioned, each character folder has character trait files in it. I'm using a nudemod so all of the files are inner armor files. I can't say for sure, but you can probably get hair files or tattoo and makeup files in there. I don't know for certain, though.
I've made this post long enough as it is so I don't really want to post all of the inner armor files. If you really want them, I'm sure you can use a search engine and find them somewhere. They follow the same file type rules as the armor. .dx80.vtx, .dx90.vtx, .mdl, .sw.vtx, and .vvd. I don't have all the folders, I don't think, but this is probably enough for whatever it is you're trying to find. Enjoy.
