Soperwillton Five-Piece Shoulder Tote Set

Thirteen inches is the width at which a letter-size folder stops bending at the corner, and this is the bag that has it: 13 across, 10.3 tall, 5 deep, on a 10.7 inch shoulder strap that hangs the bag at the hip and clears a winter coat.

Five pieces come in the box and each one is a finished bag. The crossbody is roughly two thirds the width of the tote and carries its own adjustable strap; then a zip wristlet, a folding wallet with card slots and a coin section, and a card holder. It is the deepest box in the catalog, and the reason to take it is that the evening bag is decided before you go looking for one.
