Late 60's hand sewn formal dress

My sister belong to the Order of Rainbow Girls back in late 60's to 70's. This hand sewn formal dress was made by our mother for this organization. The photo's don't do justice as the the color is a fire engine red with a beautiful cutout back with bow. Measurements are: 38" long; 14" waist flat; 17" flat arm pit to pit; 22" bottom flat hem; 17" inner sleeve; 4" flat sleeve opening; 7.5" zipper; Back cutout is 14" x 6". No snags, rips, stains or tears. As perfect as if it were made yesterday!
