For the most part, the terms “attaché case” and “briefcase” are practically interchangeable. But, when you compare an attaché case and a briefcase side by side, there are some minor distinctions. An attaché case is a small, thin suitcase that opens into two distinct compartments that are usually symmetrical. Additionally, attaché cases typically feature a leather or metal exterior and a slim profile for easy hauling. Historically, an attaché case would not include a shoulder strap, but current models often include one, like our Jefferson brown leather attaché. On the other hand, a briefcase is a flat, rectangular container that opens into one primary compartment which then has a “lid” that may have pockets or gussets that expand to an attaché case, allowing for more robust storage. Like an attaché case, a brown leather briefcase from the old days would not include a shoulder strap, but today they often feature one to suit modern professionals (like our Jefferson modern brown leather briefcase).
