Well, you can buy Comfortable Clothes from Geoff at Mhenga scrap shop. They obviously won't give any real combat utility but I tend to change into them when I really want a casual look for Steele. Same for Business Clothes for formal occasions. But if you really want a wild gunman look with the jacket and all there is the Protective Jacket. And if you want better armor but still look stylish, use Lighting Duster. Electric Resistance is always good.
