Kelin Rivera

Two years later, the Miss Peru organization featured a reestructure due to incidents early in the year and called for a special edition of the 2019 pageant, where it was a requirement to have previous pageantry experience at the international or national level. Only ten candidates where selected in a rigorous casting call and interviews to compete for the national crown. On the night of October 20 and cited as a favorite for the title, Rivera went on to become Miss Perú 2019 on her third attempt at the crown at age 26.

She represented Peru at the Miss Universe 2019 pageant in Atlanta, Georgia, where she was a Top 10 finalist. Rivera was the 19th Peruvian to place in Miss Universe history.

The following year on October 29, 2017, she returned to the country's national pageant (in order to participate in 2018 events) and for the second time finished as 2nd Runner-Up. Her placement here gave her the chance to represent Peru internationally again, at the Miss Eco International 2018 pageant in Cairo, Egypt, where she placed as the 2nd Runner-Up.

Having taken a break from pageants to focus on her studies, she came back in 2016 where she won the national collegiate title of World Miss University Peru 2016 in order to participate at the international level for a second time. Rivera traveled to Beijing, China to represent Peru at World Miss University 2016, where she defeated 56 other candidates from across the world to become the first Peruvian and first South American to win the title. She was crowned by the outgoing titleholder, Karina Martin from Mexico.

Having started modeling as a teenager, Rivera's first adventure in the world of pageants came at the age of 18, when she participated in the Miss Peru 2013 pageant for the first time on June 30 of 2012, as one of the youngest candidates in that year's edition and placed as the 2nd Runner-Up on the final night. Thanks to this result, it gave her the right to represent Peru at the Reina Hispanoamericana 2013 pageant in Santa Cruz, Bolivia. She won the special award of "Miss Elegance" and despite being cited as a favorite for the title, she did not place among the Top 10 finalists more likely due to her young age and not much preparation.
