I am new to this so it very well could be that my mesh isn't very good

I am brand new to making my own mods, I successfully made my own armor for the player to craft and wear. The problem is I am trying to make a world model to go along with the actual armor and whenever I apply the material file to the mesh in Outfit Studio or Nifskope the textures end up looking all weird and stretched out. I'm sure it is something really simple that I missed or forgot but I can't figure this out for the life of me. I've never made a post asking for help troubleshoot something before so I don't know if I am breaking any rules or what have you, if I am please let me know and I will adjust what I need to. If anyone can offer their two cents about this problem I would appreciate it very much. https://imgur.com/a/Te1kJik - a link to show the texture issue I am talking about.
