I remember reading in an earlier post that the robe models from KOTOR I were included in KOTOR II but unused. Is this true? If so, how do I use them?

The robe model is indeed included in TSL. I have done this in my Movie Jedi Robe and Armour mod. (http://pcgamemods.com/mod/11687.html) You could have a look at that and see how I did it. There is a readme included that shows how the files were modified. Basically you have to alter the appearance.2da file to point to the old model. Feel free to post any questions. :)

What do you mean "point to the old model"? I'm a little confused. Also, are these only available to the PC?

NO, in the holowan plugin for tsl, the new clothes model is the jedi robe from kotor 1. So u could put in the old skins, or make new skins, its up to you, its easier for u to make the robes u want (kotor 1 model) if u get the holowan plugin.
