Vintage denim skirt

Lee casual vintage denim skirt. There are some spots on this skirt that I have not tried to get out. One on the back center down at the hem that one is super light and can hardly be seen. Others are on the left side seam at the bottom of the skirt. Otherwise in great condition. Vintage size 13 which I believe is around a size 12 now. The waist 15 inches across laying flat.
