These two Australian models are no stranger to being in front of the camera.
But when size 6 model Georgia Gibbs and her size 16 friend Kate Wasley took a picture on Sydney Harbour and posted it online they were seriously shocked by the hate it attracted.
"We posted this picture, just as best friends going out on the weekend, it got reposted a lot and the controversy started," Miss Gibbs wrote on Instagram.
You have photoshopped yourself thinner or your friend bigger, what kind of friend are you? Was one of the comments, it broke my heart because Kate and I are best friends why would I do that? The fact that a simple picture of two people together went so viral purely because of their body types shocked me... and @any.body_co was created because no one should have to deal with that and it shouldn't even be acknowledged, all I see here is two women.. not one "skinny" woman and one "curvy" woman, stop comparing everyone to each other and accept every person as beautiful in their own right. #loveanyBODY
"'You have Photoshopped yourself thinner or your friend bigger, what kind of friend are you?' was one of the comments. It broke my heart because Kate and I are best friends why would I do that?
"The fact that a simple picture of two people together went so viral purely because of their body types shocked me."
Miss Gibbs and Miss Wasley saw the photograph as the light bulb moment they were looking for.
"People aren't used to seeing girls of different sizes photographed together and being okay with it.
"It's not often that a healthy body is marketed to us in all different shapes and sizes.
"We want girls and women to stop comparing themselves to others because we are all so uniquely beautiful in our own way,' said Miss Wasley told Daily Mail Australia.
And their method of promoting positive body image is through a newly created joint Instagram account which already has 46,000 followers.
Photographer Chris Mohen took some incredible images of the girl beach-side to show the haters that size means nothing.
"Health is more important than size and healthy bodies come in many different shapes and sizes.
"We all have imperfections and things we are insecure about but we are all human and these things are normal and beautiful. They make us who we are," said Miss Wasley.
Miss Wasley and Miss Gibbs are the best of friends away from Instagram.
They exercise and eat very similar things. They live in the same city. They earn money doing the same job. The only difference, they say, is their body shape.
"A typical girl date for us would be driving to the beach blasting Beyonce and singing at the top of our lungs, followed by a healthy lunch, something active maybe a coastal walk, gym or Pilates then chilling out together watching TV.
"We often spend the entire day together!' said Miss Wasley.
Their Instagram account shows the girls frolicking on Bondi Beach together in black bikinis.
Inspired by their original side-by-side photo, these ones have been shot in an effort to say women look different, so what?
"It's awful that people feel the need to comment negativity, but of course everyone is entitled to their own opinion.
However the way you treat others is truly more of a reflection on them than it is us and it really shows that there are so many people out there who don't see that healthy comes in all shapes and sizes and that healthy people can have cellulite, stretch marks or bones showing," said Miss Wasley.
As for the modelling industry and its condoning of various shapes, Miss Wasley said the girls are making it work for them.
"Personally I think because our bodies are our work it's hard to fight the pressures of being a certain size. But we have both embraced what we have," she said.
