Gunne sax black label folk art 1960’s dress

Absolutely stunning gunne! Rare, you don’t find this one much! Has a few small holes under the arm pit and at the shoulder seam. The cuff snaps need to be sewn back on and missing one or two of the small snaps at the cuffs. Tried to get most of flaws in the photos. This is not perfect but no major huge holes or rips to the main part of the fabric No size tag. Please see measurements. Maybe a 3/5? Pit to pit - 16.5” Shoulder to hem - 51” Waist - 14.25”
