What to wear
Visitors to Qatar should be aware of the dress code when outside of their complexes. Qatar is a Muslim country and as such women are expected to wear modest clothing, no shorts, short skirts or exposed shoulders/cleavage. At the main hotels and on the beaches, it's okay to wear this kind of clothing.
