A self-proclaimed “body neutrality advocate,” Sixtine uses her platform in the hopes of inspiring others to embrace their bodies regardless of their shape or size. She has modeled for notable brands such as Target, Warby Parker, Ulta, SKIMS and Aerie. Born in Brussels, Sixtine and her family moved to Fort Worth, Texas, when she was 3 years old. She moved to New York City at the age of 18 to pursue a career in modeling and attend NYU’s Gallatin School of Individualized Study, where she obtained her B.A. with a concentration in psychology, human rights and politics, with a minor in child and adolescent mental health studies. Sixtine makes her SI Swimsuit debut in the 2023 edition.
