Vintage 1970s Gunne Sax skirt

Authentic Gunne Sax skirt from the 70s. Sat in a box in my grandparents closet for 40 years and then in mine for 10. Brand new condition without tags. Tag says size 5 but I’d say it fits a 0/2. I am moving overseas and need to downsize that is the only reason I am letting this skirt go.
