Under the Saudi Arabia's strict dress code for women, Saudi females are required to wear a headscarf and loose, black robes in public
Michelle Obama, wife of America's President, Barrack Obama has been criticised after she went without a headscarf in Saudi Arabia.
Reports say there was an outcry by citizens of the Islamic country against the first lady's dressing - long pants and a long, brightly colored jacket but no headscarf, as she joined her husband for a condolence visit after the death of the King Abdullah.
Under the kingdom's strict dress code for women, Saudi females are required to wear a headscarf and loose, black robes in public.
Most women in Saudi Arabia cover their hair and face with a veil known as the niqab.
But covering one's head is not required for foreigners, and some Western women choose to forego the headscarf while in Saudi Arabia.
It was gathered that a delegation of Saudi officials - all men, greeted the Obamas in Riyadh on arrival.
Some shook hands with Mrs. Obama, while others avoided a handshake but acknowledged the first lady with a nod as they passed by.
However, some people took to twitter to express their opinion on the 'headscarf' issue.
