Visitors to Saudi are expected to dress in a conservative, smart fashion.
Men should wear suits and ties for business meetings, despite the heat and women should wear business suits (not trousers) which leave as little flesh showing as possible. Skirts should be well below the knee and preferably ankle-length. It is also advisable for women to carry a headscarf.
It is not advisable for men to wear traditional Saudi costume as this may seem bizarre or even offensive behaviour to local Saudis.
The correct observance of dress code is monitored by the Matawain (religious police) who are responsible for the enforcement of modest dress in accordance with Islamic law.
