Vintage Jackie O type formal dress with long jacket size 2/4 salmon chintz

Stunning vintage unlabeled except for ILGWU union label which dry cleaning ruined because of age of label couldn’t be helped. Estimate to be size 2 or 4 based on measurements. Needs further seamstress work to secure buttons. Dress zips very smoothly like butter. Jackie Onassis era dress 1964-1973. Prob for a collector. Chintz material. Salmon in color. Had it professionally cleaned.
