Miss Tahiti 2018 Chaves began her pageantry career competing in
Miss Tahiti 2018. She went on to win the competition on 22 June 2018 in
Papeete and was crowned by outgoing titleholder Turouru Temorere. As Miss Tahiti 2018, Chaves earned the right to represent
French Polynesia at the
Miss France 2019 competition held in
Lille.
Miss France 2019 Preparations for Miss France began in November 2018, with Chaves traveling to
Paris for pre-pageant activities,
Mauritius for the pageant's overseas trip, and then to Lille to begin rehearsals. The finals were held on 15 December 2018, at the
Zénith de Lille. Chaves advanced from the thirty contestants to the top twelve, later also advancing to the top five. She went on to be crowned
Miss France 2019 by outgoing titleholder
Maëva Coucke, with her first runner-up being Ophély Mézino of
Guadeloupe. Chaves was the first Tahitian representative to be crowned Miss France in twenty years, after
Mareva Galanter was crowned
Miss France 1999, and only the fifth Tahitian crowned ever. Following her win, Chaves became a knight of the
Order of Tahiti Nui, one of the highest civilian honors in French Polynesia. On 25 June 2019, Chaves announced that she would not represent France at
Miss World 2019 or
Miss Universe 2019, as she would rather accompany the contestants of
Miss France 2020 during their trip to Tahiti, which would have conflicted with preparation for the international pageants. Her first runner-up, Ophély Mézino, was appointed as Miss World France 2019, while her predecessor,
Maëva Coucke, was appointed to represent France at
Miss Universe 2019. She completed her reign on 14 December 2019, after crowning
Clémence Botino as her successor during
Miss France 2020. ==Post-pageantry==
