"Pachucos" perform during an exhibition of ballroom dancing as part of a tribute to Mexican artist "Tin Tan" at the Cultural Poliforum Carranza in Mexico City on August 27, 2017. Wearing their feathered hats, colorful tank tops, gold chains on the lapel and patent leather shoes, the Pachucos - the subculture that characterized Mexican gangs set up in the United States in the 1940s - continue to dance to the rhythm of legendary mambo in salons in Mexico.
