Vintage women’s leather jacket

This was my moms from the 70s. Basically perfect condition. Waist is a little tight on me. It measures 17” across the bottom and 21.5” from shoulder to bottom. Arm is 24.5” from seam to wrist. Armpit to armpit is 18”. Any questions lmk. Fits like a size 4-6. The tag says size 34, after doing some research a euro size 34 top is a size 4 US. Please compare measurements to similar item.
