EUC Vintage Lilly Pulitzer pattern from 1973

EUC vintage pink floral bridesmaids dress kept in pristine condition since my mother’s bridesmaid wore it in 1973! Handmade by my great grandmother in Florida from Lilly Pulitzer hand printed fabric (from a company called Key West). Size is unknown but measurements are in photos and happy to answer any questions! I sized it at a 2 based on 14” waist when laid flat. Open to reasonable offers
