NWT Zara mid rise regular length bootcut fit slate blue jeans in size 8

Zara blue slate color jeans Size 8 Bootcut fit Mid rise 100% cotton Full length Zip fly There is some light dirt staining (see pictures) on the front of one of the thighs of these jeans. The dirt would likely come out in the wash but I am not attempting to remove it because I don't want to take off the tags and wash it!
