A type of durable woolen fabric, usually dark brown or black, historically used for making clerical robes, academic gowns, and formal wear.
From French brunelle, possibly related to the adjective 'brun' (brown); the fabric became associated with serious, formal occasions because of its sober color and dignified appearance.
Brunella fabric was what scholars and clergy wore because it was practical, long-lasting, and conveyed seriousness—your outfit literally told people you were educated or religious.
