/ˈkɔrpərət ˈkæʒuəl/ – Phrase
Definition: Trang phục công sở thoải mái.
A more thorough explanation: a dress code in some law firms and other organizations whereby lawyers and other employees can wear less formal clothes than business clothes, but which still give a professional and businesslike impression eg for men, trousers and a shirt, but no tie
Example: Jeans and a tee-shirt do not count as acceptable corporate casual.
