J brand straight leg (so soft!) jeans 25

The fabric that these jeans are made from is hard to describe! It's very thin and stretchy and so soft- it's not a traditional 'denim'. They're a very dark blue. Straight leg. Measurements: waist 13.5", rise 7", inseam 29". There is an area on the fly and just below it where the fabric is slightly faded- it's more obvious in photos than it is in real life. Otherwise no flaws.
