My wife wears a headscarf and sometimes a full Arabic veil when outside in the world. The modest dress of Muslim women is very appealing to me. A long dress and headscarf, and sometimes a full Niqab or Burqa gives an impression of feminine modesty and spirituality. It also affords women a sense of seriousness, of submissivesness, of privacy, and of peacefullness.
Such dress need not be plain. My wife has have scarves, long dresses and veils in a variety of materials and colors.
The wives of the Prophet covered themselves. Modesty and Submissiveness is a virtue.
