So Hot! Sydney Sweeney And Elsa Hosk Prove This Sexy Bikini Trend Is Here To Stay

The 24-year-old Euphoria star wore a black Palm Swimwear 'Viper' bikini top in a fun and sexy picture she shared to her Instagram, while the 33-year-old former Victoria's Secret model made a case for the bikini trend by pouring her curves into a Barbie pink Sommer Swim 'Xena Profumo' halter bikini top, which she kindly also shared to her social media on April 20th.

Among the many approving comments from Elsa's fans was a comment from the minimalistic luxe swimwear brand itself, which wrote, "You look amazing in our bikini," followed by a red heart emoji. We couldn’t agree more! Oh, and we love Elsa's contrasting crochet Orchard & Ito bucket hat too!

For anyone who is still a little confused about what the trend actually is (don’t worry, you're not alone) the look essentially involves positioning the gathered part of the bikini top, which usually sits under the breasts, at the sides instead, creating a sort of upside-down effect. It's got nothing to do with Stranger Things, and is just a fun new way to experiment with fashion. Who knew that wearing something a different way than originally intended would be *so* hot?!
