There are no formal attire events, so you can leave the Tuxedos and Gowns at home (unless you want to wear them). If you bring Business casual clothes you will be welcome at at all events and venues.
Business casual means t shirts, shorts and tank tops are fine for around the pool, at the beach Olympics, the BBQ etc. For the evening events gentlemen should wear pants (dockers are fine, thats what I’m wearing) and a collared shirt. Casual loafers or boat shoes are fine. Sneakers are frowned on by some of the snottier Miami clubs. Ties arent needed.
Ladies can wear a dress or pants and blouse.
