There is a dress code at all formal dinners defined without reference to gender identity or expression. At Formal Halls and Supervisors' Evenings this is a lounge suit/jacket with a tie or appropriate equivalent attire. College Members, and guests who are members of the University, are encouraged to wear gowns. Persons wearing a shirt without a jacket and tie, or appearing in jeans, training shoes, beach footwear, and/or hats or caps, will be refused entry. If you are unsure of the requirements – please consult the Butler before the event.
