A: If you're lucky to attend a mouthwatering and festive luau, you may want to dress the part. Comfortable clothes are always appropriate in Hawaii. Most ladies wear nice shorts, pants, or a casual tropical sundress. Men typically wear khaki shorts or jeans with an Aloha (Hawaiian) print shirt. You might want to bring a light sweater in the winter months, as after the sun sets, it can get slightly chilly.
