Supermodel Christy Turlington is known as the face of Maybelline, but now she's also one of the faces of PRODUCT (RED)™! As a mother of two, Christy says the idea that a mother can't get medication for her child is unfathomable.

Dressed in an "INSPI(RED)" tank top and olive "DESI(RED)" T-shirt, Christy makes a surprise appearance on the Gap runway. The safety pin attached to her shirt is decorated with African trading beads, which are customarily used in Africa in place of money.

Proceeds from Christy's outfit would help 58 pregnant women prevent the transmission of HIV to their unborn children.
