A shoulder bag is generally any bag with a strap long enough to be slung over one shoulder. Shoulder bags often feature adjustable straps and are typically designed to sit between the waist and hip. Similar to messenger bags, the shoulder bag’s strap is looped over the shoulder, allowing you to carry the bag hands-free. Etsy shops sell handmade and vintage shoulder bags in a wide range of styles and materials, making it easy to find one to match your personal aesthetic.
