Parker Crawley Black and White Dress

Parker black and white colorblock dress. Adjustable spaghetti strap dress and V-neck. I purchased this a few years ago and have never worn it, so it’s in nearly perfect condition except for one faint stain on the front (see photo showing front white section). It’s barely visible, but I’m not sure what it is since I’ve never worn the dress. I think a dry cleaner would probably be able to easily get it out.
