For the best visual of how a country's economy and political landscape has changed, there is no better place to start than with the beauty and fashion trends of women.
They are a shopfront for shifting ideals, moods and conservatism.
In 1910, women sported monobrows and had pared-down make-up, with a close-fitting hijab.
A decade later, the hijab becomes looser and softer around the crown of the head, reflecting social changes - the Iranian social movement for women began.
In the 1930s, the Shah of Iran Mohammad Reza Shah Pahlavi implemented big changes - starting with the name of the country from Persia to Iran, and banned the hijab.
We can see hair getting more elaborate, make-up becoming heavier and looks that reflect Western trends.
Then the revolution occurs in 1979 and is evident in the sober, black hijab and face devoid of make-up.
But, while these were dark times for many Iranians, hope flourished again with the Green Movement, which sought to bring about political change after the 2009 presidential election.
While the hijab - now mandatory - remains until the 2010 look, it becomes more colourful and once again, a bit looser.
A hopeful sign that, like beauty, no political landscape remains the same.
