An indigenous group from the region, where the pearls were collected, Sambilog-Balik Bugsuk Movement, published an open letter to the eventual winner, Kjær Theilvig, condemning the crown designers for its ties to the "suffering of Indigenous Peoples in Bugsuk Island" and urging her to use her platform to highlight the issues faced by marginalized groups around the world.

[49] After the preliminary competition, special awards were given to the national directors and contestants who demonstrated their dedication and passion for the Miss Universe organization.

[50] The Best in National Costume award was announced on their official social media platforms two weeks after the competition, based on votes in the Miss Universe app.

The competition was sponsored by jewelry brand Mouawad and communication platform CI Talks, and the winners were determined through an online vote and a selection committee.
