Retro/vintage PATAGONIA womans size 14 pleated slacks. Cotton twill, back pockets (one button split) slanted front pockets, double seam in front. Kaki green, Waist 30/inseam 31 When recently look at the slacks, I noticed a mark on the left butt- and am unable to wash it out ( almost looks rust like?) Will post a pic so you can visualize
