Answer: Oxford Cloth Button-Down.
Oxford cloth is a thick and densely woven cotton. It’s extremely resilient – one of your workhorse kind of fabrics.
Oxford cloth dress shirts come in a variety of different collar styles from forward point to spread collar.
However, the most common collar for Oxford shirts is the button-down collar. Thus, the term we’ve all become familiar with – the Oxford cloth button-down.
Or, as menswear aficionados like to abbreviate it as: OCBD.
