Glasgow born singer and radio host, Tallia Storm and mum, Scottish Fashion Week founder Tessa Hartmann hosted a star-lit evening in Miami making an audacious American debut for Scottish born

HartiSWIM, the fiercely creative, eco-conscious brainchild of the Hartmann Family.

Fusing fashion, art, and ocean activism while successfully mixing eco and style, the energy was electric. The collection was a riot of vivid hand-painted pop art prints, sculptural

silhouettes, and joyful irreverence, each piece echoing the exuberant brushstrokes of Sascha Hartmann – aka Harti, co-founder and in-house artist. Dad to Tallia, husband to Tessa, his

original artwork, transferred directly from canvas to cloth, turned swimwear into walking murals.

Each swimsuit is made from certified sustainable fabric derived from 13.1 recycled ocean plastic bottles per swimsuit, meticulously transformed into luxe performance textiles.

“We’re not here to just sell swimsuits,” says Tessa Hartmann. “We’re here to educate, to connect, and to celebrate the oceans we love - with fashion as the medium.”

Rising pop star Tallia Storm, performed for the finale in a kaleidoscope of colour and craftsmanship, hand-finished in the UK.
