I'm an Inuyasha fan as well and I would really like to have Inuyasha's kimono in Skyrim, however, I'm not a pro at modding so I hope someone creates this.
It's strange, if you really have no mods and you have made sure that the load order is correct everything should be fine. Try reinstalling the game and/or starting a new game just to make sure your saves are not corrupted. Good Luck!
