The debutante ball marks girls' transition from childhood to adulthood and is common in Brazil and other Latin American countries. This particular ball was organized by the Peacemaker Police Unit program in Rio de Janeiro's Mangueira favela, or shantytown. All photos were shot on Nov. 8, but made available to NBC News today.
