Describing herself as a 'positive body activist' as well as a model, she is the size-26 beauty who has shaken up the fashion industry.
And now Tess Holliday – sometimes dubbed the world's first plus-sized supermodel – has decided to really push the boat out, posing up entirely nude.
In the gorgeous Instagram snap, which has notched up 42,000 likes since being posted, the 30-year-old includes an inspiring message for her fans.
"My relationship with my body is a journey, not a destination. I appreciate & honor what's it's done for me, & the life it brought into the world.
"I couldn't give a monkeys if you find me attractive or if my body offends you."
Ms Holliday recently criticised the likes of Victoria's Secret for not carrying larger sizes.
"Growing up in Mississippi, I definitely remember Victoria's Secret being a huge part of my teenage mall experience, but I couldn't really fit into any of the underwear," she told MTV News.
"I've never actually worn anything from there. I've never been able to."
She added: "But I think to have the biggest lingerie retailer in the world carry plus-size lingerie would be a huge step in the right direction and an accomplishment, not just for the industry, but for women in general."
Tess went on to state: "The bottom line is that there's this pervasive feeling that fat girls aren't supposed to feel sexy, and that needs to change.
"It's something plus-size women are constantly messaged – either overtly or subconsciously – and that shows in a lack of options for lingerie."
At 1.65m tall, Ms Holliday weighs around 130kg. She first pursued her career at the age of 15, but didn't start modelling professionally until 2007.
She has worked with Benefit cosmetics and H&M and has appeared in Nylon and Vogue Italia.
