Gunne Sax style Renaissance dress

beautiful vintage 70s natural fiber/ eyelet fabric gunne Sax style dress. there is no size or brand tag, but it's very well made so it's either a great home seamstress or possibly a true Gunne without tag? nice pre-owned condition,fabric isnt crisp white but i dont notice any holes or stains. I wore this as a small/ size 4 but see measurements. pit to pit 17 in, waist approx 14.5,length approx 56 in
