Qatar is a Muslim nation, and all tourists travelling to such countries make it a point to pack conservative clothes. However, laws are very liberal in Qatar which has progressed by leaps and bounds to evolve into a stylish and modern holiday hub. Hence, you may dress as you please. However as is the rule when visiting a foreign nation, one must ethically respect the customs and cultures there. Therefore, choosing to dress modestly at your own discretion will earn you loads of respect. There are plenty of 5 star hotels in Doha where modern tourists can dress as they please without offending anyone. Popular options such as Souq Waqif Boutique Hotels by Tivoli cater to the contemporary traveller.
