Please respect this rule. What to Bring Pack lightly. Comfortable, informal clothing is worn everywhere. If you see a guy with a tie and coat, he's a lawyer on the way to court. Maybe a jacket for a really up-scale restaurant but no tie.
Aloha shirts are OK for business and social events.
Sundresses, shorts and tops are fine for women everywhere. Women will want a sweater or wrap for the evening during the winter. Boots are too hot, wear running shoes or sandals. Of course, bathing suits. Hat and sunglasses go along with this.
