Vintage 1972-1975 single stitch 505's these jeans are beautiful, i can not believe the condition these are in for their age i'm saying size 25/26 because they fit as a size 26 but they are a tag size 28 which means they were made for a smaller frame and obviously haven't be washed a million times, i do put them through a scalding hot temperatured wash which 99% of the time gets them as shrunken as their gonna get i think these might shrink a bit more. So with that information and the measurements i provide make your own decision. I wear a modern size 24/25 for reference and all of mine are tag size 27. High rise, regular fitting with a straight leg in non stretch denim. Tag size 28x32all sizes are based on measurements waist 27rise 11hip 36inseam 31all my jeans are repaired and go through a sanitization wash if you have any questions please ask because all sales are final i want you to love your new old jeans.
