Summer clothing is suitable during most of the year, however a sweater, jacket or wrap is recommended for evening wear throughout the year. Although casual attire is suitable for most occasions, Tongans are conservative so moderate dress is expected. Shirts should always be worn in public places as it is against the law to appear in a public place without a shirt. Women should not wear swimsuits, low-cut tops, or very short skirts away from hotel pools and beaches.
