I thought I'd make some baggy pants.
They don't look like they are sagging but I tried...oh god I TRIED lol
FOR DAYS
I'm not familiar with programs used for the Sims. I REALLY REALLY REALLY wanted to model my own hair and cloths but until i get milkshape or learn blender that's not happening any time soon.
SO, i learned how to re-texture in game clothing to make my own package.
Currently you cannot recolor the boxers and the jeans other than solid colors.
I haven't figured that part out yet.
If you want it you can have it. Just Let me know.
