This sweater is gorgeous! It has crochet detail along the arms and ribbing along the neckline and bottom hem. It has never been worn (I bought it hoping I’d lose enough weight to fit into it- HA!) but the tags have been removed. From armpit to armpit measures 19”. 56% linen,41% rayon, 3% other fibers. **Please note you’ll want to wear a tank under this unless you’re looking for a hot date 😉**
