Vintage Dolce Gabbana silk slip dress

Dolce Gabbana midi length slip dress I have had this dress almost 10 years unfortunately at some point I accidentally washed in the machine with other clothes. It lost some luster and has some stress to the silk, I’m not sure if this is fixable. The Dolce Gabbana tag has fallen off but the interior are tag is attached on the side. A professional steaming might help revive some areas that have become muted Size 42 ( fits small medium) The dress has a lining attached 100% silk
