I bought a beautiful silk charmeuse sash to go with my dress, but it was the floor model and the last one they had. I'd like to clean it before my wedding, but my seamstress warned me that a dry cleaner could mess up the color if they don't do it properly. Does anyone know of a good dry cleaner in DC/Arlington that works well with luxury fabrics? I'm so scared of going to just any old cleaner and having them mess it up. Thanks!
