The Merine Puffy Shoulder Bag in Dark Blue by Isabel Marant is a quilted dark blue leather crossbody bag. This versatile style doubles as both a shoulder and cross-body bag, and boy, do we love a 2-in-1! Boasting a chain strap, magnetic fastening, one main compartment and two patch pockets (one of which is zippered) - this denim delight will fast become a favourite.
