Dickies Overalls

Bought these Dickies striped overalls on DePop but haven't worn. They came with some kind of strain on the right leg. I washed and dried them with no change to the stain. They're in structurally sound condition, just way too big for me. Marked a size Large, but fit like a 12/14. I'm 5'2", normally a size 8/10, and the legs are about 6" too long. I also have 42" hips and have tons of room in these overalls.
