Sixtine, who returned to the SI Swimsuit brand in 2024 for her second feature, photographed by Derek Kettela in Belize, is always our go-to content creator when we need a reality check on diet culture. Preferring the term “body neutrality” over “body positivity,” the internet personality puts a focus “on accepting your body for what it is: a body” without “the need to love it.”

While on set with the brand for her debut shoot in 2023 with photographer Yu Tsai in Dominica, Sixtine recalled having a photo of a woman holding a Sports Illustrated Swimsuit magazine on her vision board. “To me, being a rookie feels powerful and strong,” she said. “I’ve always said that I never want to be just a pretty face as a model. If I have a platform, I want to be able to use it, and being a rookie allows me to do that.”
