Hollywood is really giving the millennials their childhood dreams served up on a platter this year. Not only do we have the Barbie movie debuting in a few months, and, therefore, another year of millennial pink rebranded as Barbiecore, but the live-action remake of the Little Mermaid, too.

Last night, the film’s star Halle Bailey, who plays Princess Ariel, appeared on the red carpet for its premiere, perfectly dressed for the underwater-themed occasion in a molten blue gown from Valdrin Sahiti.

Not only did the strapless dress nod to the film through its colourway and water-look shine, but it featured a plunging neckline framed by two dramatically ruffled bustier panels that resembled seashells.

To keep the attention on her gown, Bailey accessorised minimally, opting for a pair of large diamond earrings and matching diamond rings and leaving her neck bare. She added blue eyeshadow and wore a matching blue, shimmering manicure.

Prior to the Little Mermaid’s press tour kicking off — and, likely, a lot more mermaid-themed outfits soon to be worn by Bailey — the  mermaidcore trend (yes, now all trends have ‘core’ at the end) had already been simmering.

First, Dua Lipa was confirmed to be starring as a mermaid in the aforementioned Barbie film, before Hailey Bieber posed on a beach with a sand-built mermaid tail to promote her new Rhode collection.

And if you cast your minds back to the Met Gala’s 2019 red carpet, you’ll remember a seemingly dripping-wet Kim Kardashian wearing a skintight dress by Thierry Mugler that was designed to appear as if she had just stepped out of the ocean.

Now with Bailey, our real-life Ariel, taking the trend to the red carpet, we’d say it won’t be long before we’re all wearing fishtails — okay, maybe just water-look fabrics — to party.

Bella Hadid, you’re up.
