These have a high waist band (owner folded and sewed it by half), a plastic zipper, and a low crotch. I don't know... 70's? And if you can see, both outside sides of the pants, towards the bottom, are slightly yellower/or paler than on the rest of the pants. Is this discoloration, or do you think it's just because the pleating has flattened out here and a large degree of fabric is seen? If not, is this at all salvageable? I hope so! These pants are gorgeous! But SO long!!
