A leading digital voice from the UK, Tallia Storm is also recognised as one of Britain’s most high-profile TikTok creators and social media stars, bringing a global audience to her work across music, fashion and broadcast media.
Designed and produced entirely in-house, the bespoke gown fused fashion, contemporary art and sustainability. Featuring metres of hand-applied ostrich feathers, the piece incorporated original artwork painted by Tallia’s father who paints under the name ‘Harti’, transforming the garment into a one-of-a-kind wearable canvas. Every element was handmade by HartiSWIM’s studio artisans.
I wanted to wear something unique, original and sustainable, and what better opportunity than the Grammys to wear our family brand, Harti, The artwork was painted by my father, and my mother has created a range of sustainable swimwear and bespoke atelier pieces, so this gown is incredibly special to me. I’m beyond excited and so grateful for this incredible opportunity, to be on the red carpet, seeing so many of my heroes up close and personal, truly feels like a dream.”
