With her raven hair in dark curls and classic red painted on her lips and nails, she looked every inch the vintage siren.


Rocking turquoise eye shadow and bold brows she crooned the words to the classic song into the mic. 


In her interview in Elle, she explained how she always felt herself to be a female and started expressing that in her dress and style as a teenager, which caused friction with her mother. 


She began her transition when she went to study drama at Columbia University in New York and was picked up by modelling agency IMG on graduation, becoming their first transgender model.


Swaying seductively for the shot, the camera skimmed over her toned figure, the sequin-encrusted pale purple dress hugging her every curve.


In July Hari Nef became the first transgender cover model in Britain, posing on the cover of Elle. 


Lorraine Candy, editor in chief for Elle UK, said: 'Hari defines the change that's happening in the world right now but also she fits into the specific fashion movement,' reports The Observer.


She added: 'She's intelligent and thoughtful, she understands and loves fashion and beauty. She's not defined by any one thing.'


December saw a different celebrity film an advent video each day.


And fans were given an extra treat to start off January 2017, with Love magazine releasing a video of Hari Nef giving a sexy performance of Blue Velvet.


The 24-year-old American model put on a steamy performance as she channelled classic Hollywood glamour.


Hari Nef was risen in the wealthy suburbs of Newton, Massachusetts, by a mother who worked in sales and a father in PR. They divorced when she was two.


The agency has handled some of the world's most famous supermodels including Gisele Bündchen, Candice Swanepoel and Gigi Hadid.


After being signed last year, she said: 'I’ve been told so many times that my look and my attitude were "too edgy’ to appeal to big fashion clients.'


The signing came a month after Vogue featured a transgender model on its cover for the first time, seen as a huge stepping stone in changing attitudes towards diversity and gender.
