done with this, finished it yesterday. Today I also imported ingame, so this is ready and good to go up at any time.
decided to go with the classic blue jeans look eventually. Maybe I'll make a texture pack for this at some point that has additional looks, but for now I think the blue is quite nice, I kinda missed doing something like this.
textures came out nice, but there are some screw-ups in the model that I really should've fixed beforehand. I didn't think it was that big a deal but colors/textures made them more apparent and obvious. It's smaller things like stitching in the back pockets being to close to the edge, zipper being to wide open/badly aligned, but it bothers me a little and stops this from being as good as it could've been. Still, it's usable I guess and it looks ok ingame, so it's fine. Mostly documenting/writing this for myself so I remember not to make the same mistake in the future.
