Women’s Pendleton Vintage Tartan High Waisted Wool Skirt in Size Medium

This skirt is beautiful and in good condition for being 50+ years old. The printing on the size tag has worn of. I feel like this skirt is a Size 8 as I tried on an extremely tight on my waist (I’m a 10/12) It does have lots of room in the hips. This also has pockets. I’ve looked it over and cannot find any moth holes. Yay! Please see photos for details of minimal wear and measurements to help advise on sizing.
