Button-down collar is a style of collar that is commonly found on dress shirts, featuring buttons that hold the collar points in place. While this style is widely recognized, there are other terms that can be used to describe it. For example, some people refer to the collar as a "buttoned collar" or a "button collar." Others might use terms such as "buttoned down" or "button-downed," both of which convey the idea of a collar held in place by buttons. In some cases, the term "Oxford collar" may also be used interchangeably with button-down collar, as this style originated from Oxford University in the early 20th century.
