First Time Making an Outfit Plugin- Issue

I am trying to make some custom outfits in my Fallout 4 game. I have made nif edits to other peoples meshes before and reinserted them under the same name to make custom outfits, but this time I wanted to create my own mod. I went through all the steps and got everything ready, then I followed several hour long tutorial videos to make sure everything is done correctly. The problem is I think I made a mistake in the CK but don't know where. The end result is that my custom armor is in the game, I can go to the chemlab, craft and wear it, but it is invisible.
My hair disappears (outfit has a hat) so the armor seems to be working as intended other than it just... not finding the nif? I double checked all of my materials/meshes/textures folders in my fo4 Data folder and they are in the correct place. I went through the CK to make sure that I did actually set the biped model correctly, and they all lead to the correct nif in my Data/meshes/armor/(folder) folder. I even checked my fo4 .ini file to see if that fix would do anything (even though all my other [downloaded] armor mods work fine) and there was no change there.

What could cause the outfit to be invisible? Is it just not deploying correctly? Is there a box I forgot to check somewhere in CK? I will try to provide as much information as possible if anybody has any suggestions.
