If you are unfamiliar with Pacific Islands, what you choose to wear also has a real bearing on how much you will enjoy your stay too.
Humidity can be quite high, so when packing your bags, make sure you leave behind the synthetic fabrics and stick to lightweight cotton and natural fibres. Tee-shirts, shorts, sleeveless dresses are great and don't forget to pack a sunhat and sunglasses and plenty of sunblock.
