Beautiful vintage floral one piece swimsuit

Vintage floral one piece swimming suit. Fully lined with foam bra cups, zipper & hook&eye back closure, side smocking, and blind hem Unsure of age, but I know it's 1980s or earlier Marked size 10, but see measurements in photos. Waist can stretch some due to smocked side panels, but the fabric does not stretch Incredible vintage condition, but there are belt loops and no belt present. No other flaws.
