'Underboob Bikini' Is The Daring New Swimwear Trend That'S Taking Over Instagram
And there's one thing a lot of these images have in common - the women are often wearing the latest must-have piece of swimwear.
From the 'bowkini' to the 'vagina flosser' we thought we'd seen it all when it came to weird and wonderful bikinis.
But of course, we hadn't.
A new trend is currently sweeping social media, with stars going wild for the 'underboob bikini'.
What's the 'underboob bikini', you ask? Well, I'll show you...
The daring piece of swimwear turns traditional bikinis upside down, by exposing cleavage under the top, as opposed to above.
Online fashion retailer Oh Polly are selling their take on the look and it features a cropped t-shirt bikini top with a cut-out underbust detail.
To go with this, are a matching pair of high waited thong bottoms, which also feature cut out sections and tie around the waist.
The look certainly isn't for the faint-hearted as it leaves very little to the imagination.
Oh Polly call their item the 'Spill the tea underbust t-shirt bikini' and the product description reads: "Wanna cover up, but don't really wanna cover up?
"Our cropped t-shirt bikini is gonna give major swim envy at any pool party."
The bold bikini also comes in two different colours - black and blue.
A number of people have been snapped sporting the trend, including influencer Sarah Ashcroft, who wore the Oh Polly look during a trip to Koh Samui in Thailand.
Samantha Rayner, who has over 460,000 followers is a fan of the bikini too, posing in several different variations of the style on her social media.
Geordie Shore star Charlotte Crosby has also jumped on the trend and has been photographed wearing something similar.
Some described the trend as "amazing" and said they were "obsessed" with it.
But others branded the whole thing "ridiculous".
