I really like Dockers City Chino slim fit pants, but after several washes, they aren't satisfactorily black anymore. (100% cotton is to blame?) I would have dry cleaned them, but that's a PITA for $40 pants So what's a good, straight, slim fit black pant that won't fade in regular wash and isn't crazy expensive? Am I asking too much? Or should I just Rit Dye these bad boys?
