Beautiful vintage dress/wedding dress

I picked up this beautiful piece at a vintage store in Los Angles. It is in pristine condition except for a very small stain (pictured above) and a missing belt. I’m reluctant to part with it, but I know someone out there has a need for it that I do not (maybe a boho bride?) Details: Size came off on tag but I could see it fitting anywhere from an XS-M Lace detailing Elastic waistband Fabric is very flowey and doesn’t wrinkle (maybe chiffon?)
