Most pageants may judge a woman’s beauty at face value, but not this one.

In Brazil, the “Miss Bumbum” contest is a nationwide annual undertaking to find the best derriere. This year's 27 contestants, who represent the country’s different states, were announced last week.

“Miss Bumbum 2014” will start in São Paulo on August 11. Brazilians have until November to vote online and determine the 15 finalists for the finale. This year the pageant will have a historic first after twins Rafaella and Graziella Fornazieri, representing Alagoas and Ácre respectively, entered the contest.

Dai Macedo, a 25-year-old model with a 42-inch bottom, was crowned “Miss Bumbum 2013.”

"It's a lot of work, a lot of devotion," Macedo told Agence France-Presse by way of an interpreter after winning the title. "I denied myself a lot of things. No nightclubs. No sweets. I went to the gym Saturdays and Sundays."

The winner of the pageant receives 50,000 reais (approx. $22,000) in endorsement deals and instant celebrity in Brazil.
