Vintage checked Skorts

Vintage Skorts. Checks are hard to photo so I did a close up of the pattern.. These look like shorts from behind and a skirt from the front. They are about 35 years old. The tags have faded but the material has not. The zipper works perfectly.. There is a thread snag in the back bottom of shorts see photo 5. Just need a needle to push it back thru. They wash and wear nicely. Waist measures 40" so that makes them an 18? Nonsmoking home, I offer a bundle discount or make me an offer.
