I had some post about the way Iranian women wear Hijab on my older blog but these days it is a hot topic in Iran. THEY started to involve with women who wear tight uniform and make up or in the other words women in attractive appearance. What really make a woman attractive?! Wearing light colors, make up, visible hair, tight cloth…Right! You found the answer of your question that why most of Iranian women wear black!
As a Muslim girl, I choose to have a suitable appearance in the way my religion asks but I do not agree with something they ask Iranian Woman to do. If THEY let women to appear in their optional way, they would never make such stupid styles. A Compulsory Hijab never works!
