Can anyone tell me a cool clothes mod that doesn't require you to make a new game but to load from a saved one? Any cool clothes mods will be fine. That is meant for assassins but any will be fine.

I'm not sure why you still think that most mods require you start a New Game. Very few mods require that.
I explained it to you http://www.gamesas.com/index.php?/topic/1114222-morrowind-mods/page__view__findpost__p__16352578

Here are some of my favourite clothing mods:
