Madeline Stuart, the Australian-born, the first professional adult model who strode down a runway for New York Fashion Week (NYFW) in 2015, continues her triumph journey in the 2018 NYFW. /VCG Photo

She was 18 when she decided to be a model. The young model struggled with her disorder of Down's syndrome – being overweight and limited speech, experiences that her mom says many people with Down’s syndrome go through. /VCG Photo

Her disability did not hinder her from pursuing her dream, as her mother described her as a tomboy, someone who would “throw a football with the guys.” /VCG Photo 

“People with Down’s syndrome have a very, very strong will and can be super stubborn,” she said. /VCG Photo

To date, Stuart has strutted more than 60 catwalks in cities including London, Paris and Dubai. She also has her own fashion label. /VCG Photo
