These jeans were designed by Hedi Slimane for Saint Laurent's Fall/Winter 2013 collection.
They're slim fitting, dark blue denim with a standout silver chain detail across the front.
The design is inspired by rock, which was a big theme for Slimane at the time. They're made in Italy, slightly stretchy, and fit very skinny most people size up. Because they were made in limited numbers, they're rare and highly sought after.
