My clothes keep shrinking (legs and arms going really short, too, so it's not that I've just put on weight!) even though I always wash on a 'mixed fabrics' setting either 40 or 30 degrees. I got a new washing machine about a year ago. Is it possible I'm doing something wrong e.g. overloading or something? Or likely a problem with the machine itself? I'm getting really frustrated and loads of my clothes are ruined. Any advice welcome!
