It's rather like having to wear a hat. Fine, if she wants to. It doesn't look bad on her.
Americans have their own style of dress, too. They should be able to get away with dressing their way abroad, just as America accepts the dressing customs of other countries.
It bothers me because Mrs. Clinton, former First Lady of the 42nd President of the United States and present 67th Secretary of State doesn't have to wear it, not in her lofty position. It sets a precedent for all Americans in that country where women must wear headdresses.
Why doesn't Mrs. Clinton lose the headgear and get photographed driving a car to make more political points for women abroad?
