Pageantry
Miss France 2018
Coucke started her pageantry career in 2013, when she was crowned Miss Boulogne 2013. In October 2016, Coucke was crowned Miss Pévèle 2016 and therefore, was allowed to compete in the Miss Nord-Pas-de-Calais 2017 competition. On 23 September 2017, she was crowned Miss Nord-Pas-de-Calais 2017 in Orchies, then represented Nord-Pas-de-Calais at Miss France 2018. Coucke won the competition, and was crowned Miss France 2018. She is the third woman from Nord-Pas-de-Calais to win the title, following Miss France 2016 Iris Mittenaere and Miss France 2015 Camille Cerf. Coucke began to raise awareness for breast cancer after her mother was diagnosed with the disease in 2012. As Miss France 2018, she promoted the development of breast cancer prevention and screening. She was involved in make-up and dance workshops in hospitals to help women undergoing cancer treatment feel more confident in themselves. On 1 October 2018, she launched the Breast Cancer Awareness Month at the Eiffel Tower which was lit up in rosy pink lights to support Breast cancer awareness.
Coucke represented France at Miss World 2018, where she placed in the top 12. At Miss World 2018, she won the Top Modelfast track event, giving her direct access into the top thirty. She is the first French representative to win the Top Model event. She was also Top 5 in the Multimedia competition and won the first round of the Head to Head challenge.
Miss Universe 2019
After Vaimalama Chaves opted not to compete in an international pageant, the Miss France Organisation confirmed on 23 September 2019 that they had appointed Coucke to represent France at Miss Universe 2019. During the swimsuit competition she slipped and fell down right in front of the photographers. The incident was widely reported in the Francophone media but it did not prevent her to place in the top 10, likely because her fall was caused by the overly slippery floor of the venue, as evidenced by the fact that four other contestants tripped or fell exactly at the same spot. In the end she entered the top 20 as one of the five semifinalists from the Europe region and finished the competition in sixth place.
