The Bosnian model started his career at the age of 17 in Australia. Two years later, he officially made his debut appearance closing the Spring 2011 Jean Paul Gaultier show in Paris. That same season he walked for designers John Galliano, Raf Simons, and Paul Smith.
In 2012, the androgynous model opened the Rosa Clara fashion show at Barcelona Bridal Week. For the occasion, Pejic took to the runway dressed in an all-white gown with a thin ribbon tied under the bust. He also wore some magnificent platform shoes that immediately gained rave reviews.
In 2011, Pejic was revealed as the new face of Marc by Marc Jacobs, and was also photographed for the Spring campaign by Jean Paul Gaultier.
Pejic is interested in politics and enjoys reading all kind of texts written by Karl Marx.
