LL Bean white jeans

Size 16 LL Bean white denim jeans straight leg. I wore these one day and just felt the waist was a little snug. The only damage that I can see is that there seems to be some sort of a rusty color Spot on the right knee, which I have taken two pictures of. I have not attempted to try to spot treat this but it is not noticeable when they are on. These come from a clean, non-smoking pet friendly home.
