Women's GRLFRND Jeans, The Helena, Size 27, Blue, NWT

These are new with tags, size 27, light wash, distressed, straight leg jeans by the brand Grlfrnd in the style Helena. They are made of 100% cotton and have a high waist with zero stretch with a classic five-pocket design and a button fly. The jeans have a small yellow-brownish stain on the back of the left leg (detailed in photos). I'm not sure what it is and have not attempted to remove it because I didn't want to wash them. The jeans are in new condition and have no other visible imperfections.
