Dress code

  • Aloha casual is the dress code almost everywhere; resort restaurants may ask for collared shirts and closed shoes for men.
  • Swimwear is fine at the beach; add a cover-up for shops and restaurants.
  • Use reef-safe (mineral) sunscreen — Hawaii bans oxybenzone and octinoxate sunscreens.
