Larissa Neto, a muse of the Unidos da Tijuca Samba School, poses as she wears a carnival dress in Sao Goncalo near Rio de Janeiro, Brazil, February 3, 2016. Rio de Janeiro's carnival parades are known the world over for the glitz and glamour, high-tech allegorical floats and shimmering bodies, which battle it out each year for the championship title. Each school is fronted by the Queen of the Drums, who dances alongside the raging percussion, and her court of sparkling, sculpted dancers known as “muses”. (Photo by Ricardo Moraes/Reuters)
