We've seen some bizarre swim wear trends as of late - from the underboob bikini to the towelkini.
There was also the drawstring bikini, which saw women pulling their straps tight, leaving very little to the imagination.
But this bizarre look has just been given an update by Playboy model Cassandra Sienega who took the style to new extremes while celebrating her birthday.
In a snap on Instagram Cassandra, who posts under the username cjsparxx, showed off a pink bikini that barely covered anything and has been branded "the world's tiniest" by one fan in the comments.
The unusual swimming costume is made from three very small scraps of pink fabric, which are just held onto her body by see-through strings.
The bikini is so small, that if you saw her from the back, you'd be excused for thinking she was totally naked.
Obviously many people approved of her choice of swim wear, telling her how great they thought she looked.
But there were some who couldn't resist poking fun at the whole thing.
One person compared the bikini to bandaids (plasters).
They said: "Should have just used bandaids."
Another wrote: "And setting the record for worlds tiniest bikini."
A sarcastic user commented: "Soo much material on that bikini! What are the washing instructions?"
While another posted: "You're too covered up in this photo."
Others said she looked "mind blowing" and "amazing".
According to News.com.au, the bikini is from SnSbikinis, a brand that is known for being the “sexiest swimwear and clothing” and often features in publications such as Playboy, Maxim and FHM.
Cassandra's post, which shows her leaning against a glass wall by a pool has now accumulated more than 39,000 likes.
She captioned the photo, saying: "Celebrated my 34th birthday in style at @thesapphirepool with friends. Hands down the best birthday EVER! I’ll definitely be back!!!"
