Discrimination against the women wearing the headscarf or chador was still widespread with public institutions actively discouraging their use, and some eating establishments refusing to admit women who wore them. A few years prior to the Iranian revolution, a tendency towards questioning the relevance of Eurocentric gender roles as the model for Iranian society gained much ground among university students, and this sentiment was manifested in street demonstrations where many women from the non-veiled middle classes put on the veil and symbolically rejected the gender ideology of Pahlavi regime and its aggressive deculturalization. Many argued that veiling should be restored to stop further dissolution of the Iranian identity and culture, as from an Iranian point of view the unveiled women are seen as exploited by Western materialism and consumerism. Wearing of headscarf and chador was one of main symbols of the revolution, along with the resurgence and wearing of other traditional Iranian dresses. Headscarves and chadors were worn by all women as a religious and/or nationalistic symbols, and even many secular and Westernized women, who did not believe in wearing them before the revolution, began wearing them, in solidarity with the vast majority of women who always wore them. Wearing headscarves and chadors was used as a significant populist tool and Iranian veiled women played an important rule in the revolution's victory. Since hijab was legally imposed on all Iranian women in 1984, post revolutionary Iranian women's fashion has seen Iranian women attempt to work within the narrow confines of the Islamic modesty code, with the typical attire gradually evolving from the standard black chador to a rousari (simple headscarf) combined with other colorful elements of clothing. In 2010, 531 young females (aged 15–29) from different cities in nine provinces of Iran participated in a study the results of which showed that 77 percent prefer stricter covering, 19 percent loose covering, and only 4 percent don't believe in veiling at all. A tendency towards Western dress correlated with 66 percent of the latest non-compliance with the dress-code. It was recently announced in Tehran that women will no longer be arrested for failing to comply with the Islamic modesty code, and violators will instead be made to attend classes given by police. There have been many changes in Iran's society in the 40 years since the revolution, often referred to as the "generation gap". This gap is overreaching and affects issues such as lifestyle, familial relationships, politics, and religion. For many of the young women one topic gaining popularity is the issue of the veil.
