​Dubai is a modern city that welcomes visitors from around the world. However, as it is also a Muslim city, there are certain factors to take into consideration in terms of dress code and behaviour.

Visitors to Dubai should dress modestly, particularly in conservative areas and public places. Swimwear is acceptable at the beach or around the swimming pool, but visitors should cover up elsewhere. Shorts and T-shirts are suitable attire in many places, although when visiting mosques, religious sites or older parts of the city, both men and women should wear loose-fitting clothes that cover shoulders, arms and legs. Women will usually be required to wear a headscarf when entering mosques.

Courtesy and hospitality are important virtues in the Arab world, and visitors will enjoy the friendliness and warm welcome provided by Emiratis. If you are invited to a majlis, remove your shoes at the entrance. Males and females will probably be escorted to different sections. If you are sharing a meal with your host, accept food and refreshment before moving on to matters of business.

It is customary to accept food and drink with your right hand; this is also the hand you should eat with. Avoid showing the soles of your feet, or pointing your foot at anyone. If you are sitting in front of an important guest, it is considered rude to cross your legs. Do not beckon or point with your finger; if you need to use a hand gesture, use the whole hand. If you are hosting Muslim guests, do not offer them alcoholic beverages or pork.
