Consider the weather conditions at the luau you'll be attending. Though most Polynesian islands where authentic luaus take place have mild to hot weather, temperatures can drop at night and there may be unexpected rainfall. So don't forget to bring along a light sweater or jacket.
Decide whether you want to go the more touristy, yet fun, route of dressing in "aloha wear." This includes short-sleeved, button-up Hawaiian shirts and shorts, khakis or white pants for men and Hawaiian muumuu dresses for women (see Resources for examples). To complete this look, opt for either a flower or kukui nut lei or bracelets.
Wear a comfortable summer outfit that you'd wear to an event other than a luau. This might be a sundress or a flowery white skirt and top for women, while men might opt for cargo or board shorts and a T-shirt. Keep up with the Hawaiian theme by placing a flower in your hair or wearing a traditional Polynesian sarong as a wraparound skirt.
Put on sandals or other comfortable, breathable footwear before you head out for the night. Luaus are traditionally outdoors, and are oftentimes at the beach, so you'll be better off wearing casual shoes you can easily kick off and that won't sink into the grass or sand.
