Vintage 70s Jack Winter Double Knit Pants, Women's Size 12, Plaid and Cuffed

Women's vintage plaid double knit pants 12, from the 1970's, in a plaid gray gold design.  These were found at an estate sale in the Seattle area.  There is a zipper in the front, no pockets with wide legs.  The tag reads, "Jack Winter, Double Knit, 100% Polyester, Machine Washable."  There are a couple of small pulls in the fabric and a whitish patch on one knee.  I have not washed there so it may come out.-inseam, 27"-length, 38"-waist, 30"-hips, 36"
