Former child star Caitlin Stasey speaks out against jeans manufacturers

Once a beloved child star on the popular Australian soap Neighbours, she's devoted much of her adult career to fighting for women's rights.

In a short Instagram story clip, she demonstrated her point by lifting up her sweater to reveal a pronounced camel toe.

Camel toe - a reference to the animal - is a term used to describe the visible definition of a woman's genitalia that can occur when constrained by tight pants.

In the video, Caitlin stood in front of a camera, wearing a large turtleneck sweater and tight, high-waisted jeans.

'Been having a consistent problem,' she said, motioning towards her crotch.

'I do feel like it's a bit discriminatory, because, like, they make allowances for men's genitalia, but women's jeans do not.'

Caitlin's Instagram contains several nude or semi-nude images of herself, and she's well-known for proudly championing body positivity.

She is a strong advocate for the 'free the nipple movement on social media.

The movement is a gender equality campaign, which ultimately hopes to convince Instagram to change its rules around female nudity.

In 2015, she co-founded the website herself.com, a body confidence project aimed at empowering women through nude photography.
