Miss BumBum is back – and voting for the title of Brazilian rear of the year has begun online.

Contestants lined up in Sao Paulo city centre on Monday as the fifth instalment of the annual competition was officially launched. A total of 27 women, one from each of the South American nation’s states, are competing for the top prize.

They’ve been whittled down from more than 500 applicants. And the 15 that receive the most amount of votes via the event’s website will go forward to a live televised pageant on November 9, according to local media. The hopefuls donned green and yellow bikinis to strut their stuff at various locations in the city.
