I have a shirt that I haven't been able to iron flat since the first wash. The shirt is striped, and the weave alternates between herringbone and broadcloth. The problem seems to be that the two different weaves have not shrunk by the same proportion. Does this sound like it can be rescued? I have tried ironing it damp and steaming it. Would it help to spray starch on it? Would the dry cleaners have a better method?
