Married At First Sight star Tamara Joy is certainly no stranger to posting raunchy photos on social media.

But the busty brunette, 31, skirted around a possible Instagram ban on Monday when she shared an image of herself posing braless in a semi-sheer green top.

The photo came dangerously close to breaking Instagram's rules on female nudity because Tamara's bare chest was partially visible beneath the flimsy fabric.

Tamara did not address her potential rule-breaking, and instead wrote a nonchalant caption about drinking margaritas.

However, her social media followers weren't exactly impressed by her raunchy display, and several fans told her to put on a bra.

'Maybe wear a strapless bra next time,' one follower commented, while another added: 'Attention seeking much.' 

However, others made light of her racy display. 

'Hopefully you didn't walk next to a car. You would have scratched it up!' one wrote, adding the hashtag #FreeTheNipple. 

Another succinctly said: 'Girl, put a bra on.'

Instagram does not allow women to share images of their bare breasts, although men are permitted to post shirtless photos.

While Tamara's chest was not completely exposed - meaning the photo didn't violate the website's rules - her nipples were visible beneath her see-through top.

Many high-profile Instagram users, including The Bachelor's Abbie Chatfield, have had their posts deleted or accounts suspended for less.  

Last month, Tamara announced she had 'turned her back' on coronavirus-stricken Melbourne and was hoping for 'bigger and better things' on the Gold Coast.

'Turned my back on Melbourne to focus on bigger and better things. Sorry Melbs, you'll always have a piece of my heart,' she told her Instagram followers.

'For now though, Gold Coast you're mine! Xoxo.'

In the accompanying photo, Tamara posed with her back to the camera in a pink bikini, while climbing the stairs of a beachside apartment.  

The reality star has made no secret of the fact she's undergone surgery to change her appearance over the years.

In addition to getting a nose job and regular lip filler, Tamara has also had a breast enlargement.
