Immy is not completely new to the world of fashion, having fronted the George for ASDA campaign last year, as well as working with brands including Urban Outfitters.
Suki Waterhouse and Immy are now signed by the same agency
The blonde beauty opened up about big sister Suki's influence on her decision to enter the world of modelling, revealing that her sibling, who has graced the catwalks of high fashion brands such as Burberry, told her not to worry too much about stereotypes.
"Suki has shown me that hard work pays off and rejection is a big part of it," Immy told Vogue. "Like Suki, I'm not typical height-wise for a model, so she advised me to just forget about those stereotypes."
Immy looks strikingly similar to her 22-year-old sibling with tousled blonde locks, a perfect pout and flawless skin.
Immy revealed she would love to model for Topshop
The young model however seems to be following less traditional ambitions when it comes to modelling. "My dream campaign would be Chelsea FC," she quipped. "I'm a stickler for football!"
That's not to say that Immy isn't keen to use her new career prospects to make an impact.
"I'd love to be a part of a change, something that turns heads, something that is hard-hitting," she admitted. "Topshop would be cool."
With Suki's close friend and fellow supermodel Cara Delevingne currently the face of Topshop, it could be that Immy has looked to the family friend for inspiration for making it in the high fashion world while still remaining quirky.
