The dress code is “formal” (similar to “black-tie optional”) which encompasses both black tie and business formal. In practice, that means if you have a tux / long gown, it’s a great opportunity to wear it. If you don’t, then a suit or cocktail-type attire is absolutely fine. We hope this dress code is more inclusive – still fancy, but not as expensive or strict as “Black Tie” and allows you to show your individuality.
