Manifesta, a U.S.-based women’s athletic-wear brand that targets women of all shapes, sizes and types, has taken on Stuart as one of their representatives.

The match seems like one made in heaven – after all, Madeline decided to become a model after she lost 44lbs (20kg) in a big to improve her health and slim down.

Stuart and her mother have been open about the young woman's struggles to lose weight and her dedication to succeeding in an industry where models with disabilities aren't common.

On Facebook, Stuart, who goes by the nickname Maddy, wrote that "modeling is changing society's view of people with Down syndrome, exposure is creating acceptance in life and inclusion."

Manifesta, is an athletic apparel brand whose goal is to make and advertise clothing for women of all body types.

"For years Madeline has fought against the struggles, both internal and external, that go along with Down syndrome," the company wrote on its website. "Through dance, swimming and cheerleading, she has worked to strengthen her heart and body. And through her modeling career, she has forced many to reconsider the conventional standards of beauty."
