I picked up my nylon crocheted sweater that was from Cach'e for about $130. This is the secound time I dry cleaned it. This time it shrank and not a little bit. This sweater is about 7" shorter, arm length and around it looks like a childs. Some of the other clothes srhrank about a size. Do you know the cause? How can this happen in dry cleaning? What can I do? Three of my favorite things are to small. Amy
