Light, breathable clothing is best for Vietnam’s tropical climate, where heat and humidity are common throughout the year. We recommend packing attire that will keep you cool, comfortable shoes, a sun hat, and a light rain jacket for your travels.
Culturally, Vietnam is a very conservative country and people dress modestly. This will be especially important when you travel outside of the major towns and cities. If you're visiting religious sites, ensure that your shoulders and knees are covered. This applies if you're visiting Ho Chi Minh Mausoleum or the countryside too. Also, you must remove your hat when entering a temple.
