An Australian fashion brand has been accused of altering the appearance of a model who is wearing its activewear on Instagram, but the company has refuted these claims in the comments section of the post.

“Hi… this model’s body shape has not been photoshopped or altered in any way,” the brand, Camilla and Marc, wrote in response to several Instagram users who left critical comments. “Please visit our website to see more detailed images or DM if you have any further questions.”

Representatives at Camilla and Marc did not immediately respond to Fox News’ request for comment.

However, multiple Instagram users are not convinced that the image is not doctored given the appearance of the model’s hands on her waist.

“Can we talk about how this photo has been majorly doctored,” one user wrote. “Her waist and hips don't appear to be in proportion.”

“This is a very disappointing photoshopped photo,” another user commented while adding that they may boycott the brand from here on out. “Really??? Might’ve just bought my last C&M piece.”
