OUR SWIMWEAR FEATURES ORIGINAL ART

Harti's art is visceral,
truth-seeking, edgy,
stirring, poking, and dark

It's a fusion of the old with the new, the Baroque with post-modern Pop-Art.

Glamour With A Conscience

The Harti girl doesn't lounge poolside like a footnote or simper from the shadows. No, she arrives with the hot, kinetic charge of an electric storm, a siren stitched not from silk but from sinew and intent. She doesn’t wear HartiSWIM; she inhabits it, as you might a manifesto, a dare, a glorious two-fingered salute to the idea that women must ever be quiet, modest, or small.

Because HartiSWIM isn’t swimwear. Not really. It's a movement in pigment and thread, a stitched-together rebellion. It declares, with a wink and a wicked little grin, that you can look heart-stoppingly good, feel even better, and - crucially - do good too. Each piece is a love letter to audacity, born from the punchy, pop-art anarchy of Harti himself: swimwear that makes no apologies, saves no blushes, and asks no permission.

This isn’t greenwashing with a better cut of Lycra, either. Every HartiSWIM suit plucks 13.1 plastic bottles straight from the ocean's bloated carcass - certified by Repreve, if you like your heroism with receipts, and turns them into a riot of colour, hand-painted, sustainable, uncompromising. While the rest of the world drowns in plastic, the Harti girl swims in art, laughing at the idea that style and sustainability must ever be rivals.

And this is only the beginning. Because in 2025, the story gets even juicier: enter Harti Atelier. Think less 'capsule collection,' more 'shimmering revolution.' Bespoke gowns, hand-embellished within an inch of their lives, each one a canvas that sashays, sparkles, and sticks two sequined fingers up at the beige tyranny of fast fashion.

Meanwhile, 1% of sales are pledged to environmental causes, because true rebellion demands action. HartiSWIM isn’t just part of the climate conversation; it’s funding the future, one ferociously glamorous woman at a time.

This, then, is eco-luxe with teeth. Swimwear to be loved, fought for, and, above all, lived in.

Harti - The Collection

‘Series 1’ is our debut capsule - and it’s anything but ordinary. A tightly curated 28-piece edit celebrating Harti’s unmistakable pop art graphics, it explores the collective subconscious through bold colour, fearless line and unapologetic energy.

Expect sleek one-pieces, audacious bikinis, statement rash guards and fluid organic silk kaftans - each hand-painted, each carrying a narrative. These aren’t just garments; they’re wearable art designed to provoke, seduce and start conversations.

At the helm is Creative Director Tessa Hartmann CBE, who founded the label with her husband, artist Harti (Sascha Hartmann). A family steeped in music, art and culture, their world is one where canvas, sound and silhouette collide, and craftsmanship is non-negotiable.

THE ARTIST

WHO IS HARTI?

But who is Harti? Harti is one of those rare creatures who, at once, is both a painter and a provocateur, a shrink and a seer. He’s a contemporary political artist, but let’s not get bogged down with labels - he’s more a cultural surgeon, wielding a brush like a scalpel. His acrylics on canvas are visceral, raw splashes of colour, each one more a cry for attention than a stroke of beauty. They’re not the kind of paintings that beg for a comfortable spot over your sofa; they demand to be noticed, questioned, dissected.

But Harti’s paintings are only half of it. The other half is the commentary - his sharp, no-holds-barred analyses of the world we’re all muddling through. His words drip with the same electric charge as his canvases.

He doesn’t just observe the world; he operates on it. He’s a kind of cultural shrink, diagnosing the ills of modern society with the precision of someone who has no patience for platitudes or weak thinking. It’s art, yes - but it’s also a blunt force therapy session for anyone brave enough to engage with it.

What the Press Say

Join the HartiSWIM Movement

Harti Swim has arrived, not with a whisper, but with a salt-kissed statement. A debut steeped in ethics, stitched with intent, and wrapped in the breezy confidence of something genuinely new. Sustainable luxury, not as apology, but as aspiration.

The response? Graciously overwhelming. Editors, stylists, and fashion’s sharper minds have taken note - and for that, we’re deeply grateful.

If you're a journalist, stylist, or creative with a flair for the future, we’d love to connect. For press or collaborations, reach us at showroom@hartiswim.com

Let’s not follow the wave - let’s shape it.

DRAPERS CONSCIOUS FASHION AWARDS 2025

Think of it as the fashion world’s version of Eurovision - minus the glitter cannons. HartiSWIM, our baby brand still in its toddler years, somehow found itself rubbing shoulders with the industry big shots in London as a finalist for Best Consumer Engagement Campaign at the 2025 Drapers Conscious Fashion Awards in London. Did we win? Nope. Did we strut out of there feeling like the Beyoncé of sustainable swimwear? Absolutely. Being in that room lit an even bigger fire under us - and trust us, this is just the warm-up. HartiSWIM isn’t going anywhere.
