Here she is!

Transgender model Andreja Pejic made her female runway debut during the Giles Deacon show in London on Monday.

The androgynous, Serbian-born, Aussie-raised stunner — who had already made a splash in the fashion world by modeling both men’s and women’s clothing — announced this summer that she had undergone sexual reassignment surgery.

Formerly known as Andrej, the 23-year-old had known she was transgender since she was an adolescent.

“I figured out who I was very early on — actually, at the age of 13, with the help of the Internet — so I knew that a transition, becoming a woman, was always something I needed to do,” she told style.com.

The catwalker seemed at ease with her decision as she took to the runway in a Victorian high-collared blouse with a pussy bow and black coat.

Sporting a Goth-inspired slick black lip, Pejic joined fellow mannequins Kendall Jenner, Jessica Stam and Lily Donaldson.
