HartiSWIM, the luxury sustainable swimwear brand founded by Scottish/British entrepreneur and brand strategist Tessa Hartmann CBE, is set to make its highly anticipated U.S. debut at Miami Swim Week The Shows on May 31, 2025.
Established in 2022, HartiSWIM has quickly carved out a space in the sustainable luxury market, blending edgy high-fashion silhouettes with a fierce commitment to ocean activism. The brand’s unique DNA lies in its vibrant pop-art graphics, created by Tessa’s husband, Harti, a celebrated composer-turned-painter whose art career evolved from therapy sessions to prestigious exhibitions across London, Edinburgh, and Venice.
Each HartiSWIM piece is a statement of “glamour with a conscience,” meticulously crafted from certified fabric made using 13.1 recycled ocean plastic bottles. With its unapologetic spirit and sustainable focus, the brand has already made waves across Europe and is now poised to captivate the U.S. market.
We are beyond thrilled to be invited to showcase at Miami Swim Week The Shows. Having only been established for three years, it’s a huge honour for an independent, wearable art brand like ours to be recognized on such an international stage. We hope this platform will mark the beginning of many exciting ventures for HartiSWIM in the U.S.”

In addition to its signature swimwear collection, HartiSWIM will also unveil the Harti Atelier at the show, a new extension of the brand featuring bespoke, made-to-order luxury gowns. The Atelier showcases the brand’s commitment to craftsmanship, individuality, and the artistry that has defined HartiSWIM from the beginning.
Tessa Hartmann CBE is a powerhouse in the world of fashion and entrepreneurship. After two decades at the helm of her award-winning fashion branding agency, Hartmann House, she was honoured by the late HRH Queen Elizabeth II with a Commander of the British Empire (CBE) for her outstanding contribution to British fashion and textiles. With HartiSWIM, she has married her deep industry expertise with a passionate drive for sustainability, proving once again that style and conscience can walk hand-in-hand.
Designed “for sirens, not sidekicks,” HartiSWIM’s #HartiGirl embodies a fierce, fearless, and independent spirit – a woman who, as Tessa proudly notes, is “never afraid to dine alone poolside.”
