I was just browsing the zbrush site for some inspiration to start sculpting. I managed to find this, I don't know what LOD (level of detail) you have planned for the suits han ung, but this is what I imagine would really look good in terms of wrinkles and asymmetry, nothing should look perfect. They sculpted the geo to make it LOOK like proper clothing and if your characters are actually wearing clothing and not metal vests this should be something to aim for. Just a thought.
