The difference in mood between the brightly lit rooms of the Cardin exhibit and the darkened rooms of "Dressing for Dystopia" was striking. The featureless faces emphasize the interchangeability of these people. The only face specifically identifiable was that of the pregnant Janine; it bore a scar where her eye had been gouged out. While the faces of the powerful in Gilead were also blank, they somehow seemed to have more stature.
Every detail in the costumes has meaning, especially their color. Art history buffs won't be surprised to learn the blue of the wives' dresses is a reference to the Virgin Mary. Still, how creepy is that?
