Luchita, a resident of Casa Xochiquetzal, colors Juanita's hair at the shelter in Mexico City, Mexico on May 25, 2016. Casa Xochiquetzal is a shelter for elderly sex workers in Mexico City. It gives the women refuge, food, health services, a space to learn about their human rights and courses to help them rediscover their self-confidence and deal with traumatic aspects of their lives. Casa Xochiquetzal provides a space to age with dignity for a group of vulnerable women who are often invisible to society at large. It is the only such shelter existing in Latin America.
