Over the past 12 months, thousands of Australian women have debuted a host of racy bikini designs on beaches across the country.
And while it was the 'sideboob' bikini that dominated the shore in 2018, this year there has been a resurgence of the 'underboob' swimsuit.
Gone are the days where simple cleavage was considered risquÃ© enough to pique the attention of other beachgoers, now it appears that near-nudity is all the rage.
Model Kristina Mendonca's latest snap on social media sees the stunning brunette push her Thalassa Swim just above her chest to show the trend in action.
Her caption was an ode to the growing underboob addiction: 'Do your boobs hang low, can you swing 'em to and fro?'
And she's not the only woman parading her assets to an audience Down Under.
Influencers Gabrielle Epstein, Olivia Mathers and Paris Clarey have all been spotted sharing photos of a similar nature with Aussie brands like Lahana and TJ Swim producing cuts to flatter the look.
Love Island Australia stars Natasha Cherie and Amelia Armani have both uploaded matching looks in black bikinis, looking very svelte after their appearance on the show.
Even The Bachelor's Sophie Tieman was getting in on the action with a bandeau-style top and high-waisted bikini bottoms.
Amy Odell, the editor of Cosmo online, told Sydney Morning Herald that women are adopting the trend again because they want to look and feel sexy.
'If you're seeing more underboob now, it could be seen as an extension of the crop top or cut-out trends that - while not new trends - have been very popular over the past few years,' she explained.
'What those trends proved is that just a sliver of exposed skin in an unexpected place can be very, very sexy.'
