Part of the message in photographer Yumna Al-Arashi’s latest project, called “Shedding Skin,” is conveyed simply by the fact that it exists. To those on the periphery of the culture, the idea of a group of Arab women allowing themselves to be photographed nude, in a hammam, or communal bath, in the Middle East seems unlikely. The stereotypical image of Arab women assumes they are devoutly practicing Muslims, wearing hijabs and long skirts and conducting themselves with religious modesty, exposing their bodies exclusively to their husbands, and perhaps to female relatives or friends behind the closed doors of a hammam. Would they allow themselves to be captured in such an environment by a boundary-pushing 28-year-old American artist, for a gallery show? In the Western imagination, probably not.
