An Eton collar is a wide, severely starched, turn-down collar made of white cotton or linen. Historically associated with school uniforms, it is characterized by its large size, stiff construction, and rounded or blunt points that lay flat across the shoulders and jacket lapels. While largely historic in everyday menswear, it remains a distinct element in formal choir robes, legal dress, and traditional boys' formalwear.
