A plus-size influencer and body-positive advocate has faced harsh criticism after recreating some of Meghan Markle's latest looks.

Katie Sturino, who says she is a US size 18 (UK size 20), posted a number of photos on Instagram with her own interpretation of Meghan's style.

But while Katie received countless supportive comments about her looks, there was plenty of nasty ones too.

Posting a picture of herself in a nude, belted trench dress, Katie included a message from a troll, that read: "She looks like she ate Meghan Markle ... and stole her dress."

And you only need to scroll through just a handful more comments on Katie's other Instagram images to find more negative opinions.

Another person wrote: "Sorry, but accepting your body that is completely unhealthy is in no way positive."

Reacting to the comment, Katie wrote: "Every time I think we have made so much progress about our bodies and the way we talk about women, something pops up to remind me our work is not done!!!

"My #SuperSizeTheLook shots with Meghan Markle got picked up and the comments are brutal...

"They do not hurt my feelings, but they are scary. It's scary that a woman who is almost the average size in this country would be regarded with such shock!
Katie says she was shocked by the amount of negativity (

"Also, they don't stop at my body, they are equal opportunity women haters who take shots at MM aswell.

"Can't be thin. Can't be fat.

"Maybe STFU ABOUT WOMEN'S BODIES!!!

"All this to say, please keep spreading positivity.

"Please keep shining bright."

She added: "Please don't engage with the crazies in the comments. Please do look at yourself in the mirror and tell her that you love her!!!!! (I just did).

"Nobody deserves to be spoken to like this, on or offline. We have work to do!!!!"
Katie says there is still work to do when it comes to how people react to women's birthdays (

Katie has built a huge social media following for sharing inspirational content, including her #SuperSizeTheLook movement, which she created to challenge mainstream beauty standards.

Writing about her project recently, Katie said: "This is never about who wore it better.

"It's about empowering women of all sizes to wear what inspires them."
