Since the Maldives is a Muslim country, you'll have to dress a little conservatively at the airport, cities and villages. A scarf along with pants or a long dress would be ideal. Once you're in your resort or island, things can get more comfortable and you can relax accordingly. Another important topic is footwear. While shoes would be your go to choice, consider switching to flip flops or sandals during your stay, since shoes and beaches don't always mix. One more piece of footwear you'd want to possess if you're planning on doing water activities are a pair of reef shoes which protect your feet from coral, sharp rocks and some fish that could hurt your bare feet.
