A briefcase is a structured rectangular bag with rigid walls, historically meant for carrying documents and papers. It is a business, status accessory associated with the professional world, seriousness and order. The classic leather briefcase with a lock clasp is a symbol of business etiquette; modern versions have transformed into elegant laptop-and-document bags while keeping the recognisable strict geometry. Unlike soft bags, a briefcase holds its shape and protects its contents, and its spare silhouette suits a suit and formal dress code perfectly. The briefcase is chosen by those who value function, organisation and classic business aesthetics. It is an accessory of authority and professionalism that gives a look a finished, confident solidity.
