Bella Hadid's January 2026 tropical vacation delivered exactly what the internet needed: a full-on mermaid era. The model posted a cascade of photos from an idyllic beach getaway — string bikinis, surfboard sessions, snorkeling adventures, and a yacht breakfast — and the internet collectively lost it. Now with her PECH String Triangle Bikini just dropping in March 2026, the story gets even better.

The "Mermaid Girl" Vacation That Broke Instagram
Hadid captioned her vacation dump simply: "mermaid girl" — and honestly, that's exactly the vibe. The former Victoria's Secret Angel was photographed in no fewer than six different bikini looks over the course of the trip, each one more envy-inducing than the last.
The standout moment? Pairing a white string bikini with peach-colored Saint Laurent lace lingerie shorts worth $4,300, styled as beach cover-up fashion. It's a move that only Bella could pull off — wearing designer lingerie as swimwear and making it look completely effortless. She also rocked a blue, red, and white gingham bikini while kneeling on a surfboard, a sleek black string bikini against dramatic ocean rocks, and a red-and-white set complete with a matching headscarf for snorkeling. The girl does not miss.
Her friends, her blonde mermaid waves, crystal-clear turquoise water — the whole aesthetic was a masterclass in how to do a beach vacation photo dump. The post racked up nearly one million likes, with fans flooding the comments with mermaid emojis and "most beautiful woman alive" energy.

And Now Her PECH Bikini Is Actually Dropping
Here's where it gets even more exciting. Buried in the vacation photos? A sneak peek at an upcoming piece from PECH — specifically, the PECH String Triangle Bikini Top in Salt Red, which officially launched in March 2026. She was literally wearing next month's drop while snorkeling in paradise, and nobody clocked it until fashion editors started zooming in.
The PECH collection is minimalist, body-forward, and feels custom — a far cry from fast-fashion swimwear. It's the kind of label that gets passed around on "where did you get that?" mood boards for months before most people can actually buy it. Bella wearing it was basically an early-access preview for those who pay attention.
Beyond the beach content, Hadid's been on a tear in 2026 — she starred in Ryan Murphy's fashion horror series The Beauty, attended the New York premiere in a red-hot wrap gown, and has been everywhere since. The mermaid vacation was a rare, sun-drenched exhale between a packed press schedule, and it showed. There was a realness to those photos — paddleboarding, snorkeling with friends, actual laughter — that fans responded to hard.
Get Bella's String Bikini Vibe for Under $40
PECH is gorgeous, but let's talk about getting that exact Bella Hadid mermaid-on-vacation energy without the designer price tag. The formula is simple: string triangle top, cheeky bottoms, bold color or classic black, minimal accessories. That's the whole vibe.
At Audi Swim, the Bow Babe Contrast collection nails it — adjustable triangle tops with a contrasting trim detail that hits the same refined-but-fun frequency Bella's working. The string ties let you dial in the fit, the triangle silhouette works on every bust size, and the contrast edge gives it a designer-adjacent finish for a fraction of the cost.
- Bow Babe Contrast Top in Pink — $17.99 — adjustable triangle string top, contrast trim, ties at back and neck
- Bow Babe Contrast Bottoms in Pink — $17.99 — cheeky thong-cut, bow tie detail, pairs perfectly with the top
- Bow Babe Contrast Top in Sky Blue — $17.99 — if you're channeling Bella's blue gingham moment, this is it
- Ocean Mist Maxi Dress in Mint Blue — $24.99 — yacht-breakfast cover-up energy, meshy and breezy
The full Bow Babe set comes in under $36 — which is, to be clear, about $4,264 less than Bella's Saint Laurent lingerie shorts. Same mermaid girl results, slightly different math.
