Basically, I want to add a pair of pants (Not too big on robes) to this. I don't really want any skin-tight pants, something a tiny bit baggy around the knees, preferably as if it were tucked into the boots (Think like the legs on the chitin armor).

 

I'm no modeller, so I'm not sure how to do that. I'm asking if someone can add them to the armor in a working fashion (Allowing it to work ingame), then I'd retex it to match the armor itself.

 

Any help is appreciated
