Dress code in Maldives

'What is the dress code?' is a frequent question on the forums. The Maldives are on the equator with the temperature rarely dipping below 25C, even at night.  Lightweight, loose cotton clothing is therefore advisable.  Please be aware that there are different guidelines depending on whether you're staying at a resort (a hotel on a private island) or in a guesthouse (in a village in a locally inhabited island).
