Note that this affects the base game as well, for example all the Master Robes of suffer from this bug. I haven't tested this with items worn on the hand, only stuff that goes on the body, however typically you don't specify a first-person texture for items worn on the hand anyway, so that scenario isn't affected by (or at least isn't as affected by) this bug.

A thing you can do in the CK is specify an alternative texture for an existing mesh, and many retexture mods do this. It works fine as far as I can tell except for one part, and that is specifying a new texture for the female first-person view. It doesn't appear to get saved to the ESP (or the ESM for that matter as this affects the base game as well). As a result, any alternative textures you attempt to apply will be ignored in favor of the default texture when viewing from the first person with a female character. Note that the failure won't become apparent until you reload the ESP (or check the results in the game). That is, you can open the dialog back up and it looks like your change is still there, however once you reload the ESP it will apparent it is not.

FWIW, Skyedit appears to save the alternative texture to the ESP, however it's ignored by the game (and the CK) anyway. When making the change in the CK and viewing it from Skyedit, however, whatever alt texture you specified isn't there. So it might be loading is bugged for both the CK and the game, and saving is bugged for the CK.

Steps taken:

• Load Skyrim.esm
  
• Make a change to an ArmorAddon, specifying an alternative texture for the female first-person view. I used MonkRobesColorGreyAA, used by ClothesMonkRobesColorGrey (10CFF1) for those who are following along at home. In that case you can specify the TextureSet MonkRobesColorGrey.
  
• At this point, it appears everything is fine. The new texture is painted on the mesh in the window, and even after exiting the dialog and going back, your change appears to be saved.
  
• Once you reload the ESP, or start the game, and try to view your change, you will find that what you did had no effect, and the first-person view for a female is still using the default texture.

Another thing you can do is just view e.g. Adept Robes or Master Robes from the first person with a female character. They'll be the wrong color. What this bug means is you can't even fix that with the editor.

This svcks.

I did come up with a workaround that should work in most cases! Simply don't specify a first-person mesh, and the game will fall back to the 3rd person one (I think that's what's going on anyway...). In the editor you would just bring up the first person model dialog, click the button to edit the model file, then cancel that dialog and save your change. That will wipe out the first person model and texture data.

The base game already does this with a few ArmorAddons like Hide Bracers and Gloves (the plain brown ones, ClothesFarmGloves03). I don't know if this is done with any body meshes, but if it doesn't introduce any errors in the case of hand meshes it's probably safe to do with anything else (knock on wood).

So, still an irritating bug, but easy enough to work around.

edit: Just to add, you need to remove the male first-person data as well. It appears that, for female characters, the game looks for a mesh in this order: female 1st person -> male 1st person -> female 3rd person -> male 3rd person. So if you don't remove the 1st person male data as well, that's going to show in the female 1st person.

Thank you so much for this work-around. I'm currently adding different colours to my mod -Thalmor Armor and this was really doing my nut in. I tried giving the female the male's .nif to see if that would work, nope. I have tested this and it does indeed work. (Thalmor anyway)

Thanks again
