Vintage Leather Coat Made in Argentina

1970's heavy tailored leather coat. No tags other than the one shown in the picture. This fits a hourglass shape like a glove, like a 1970's argentina made leather glove. it says size 15/16 but it way too small for me at a 16/18 so here are the measurements: (when laid flat) shoulder seam to seam 18" breast 18-20" smallest part of waist 17.5" bottom: 23" length: 30" arm length (top of shoulder seam to bottom): 23.5"
