Braccae is the Latin term for trousers, and in this context is today used to refer to a style of trousers, made from wool. The Romans encountered this style of clothing among peoples whom they called Galli (Gauls). This is often assumed to mean speakers of Celtic languages, though many scholars (including John Collis, Peter S Wells, Stephen Oppenheimer) doubt that the term Galli was primarily based on linguistic affiliation.
