Islam requires that a woman honor and respect herself to the extent that she does not care if a man looks at her or not.
Are you paying attention to this? A woman should be so dignified that she does not care at all whether a man looks at her or not. Now compare this with a woman who is concerned with how she chooses her clothes, her makeup, the way she talks, and the way she walks just so that people will look at her! See how different these two are from each other!
Imam Khamenei Nov. 25, 1992
