The London College of Fashion graduate took home 50,000 and produced a show at Stockholms Mercedes-Benz Fashion Week on Tuesday as part of her prize. Additionally, selections from her collection will retail in H&M stores in autumn 2012.
Riis, the UK finalist for the award, won over judges including ELLEuk.com Fashion Features Director Emma Sells with the confidence of her designs. The same strengths convinced Grand Jury members Hilary Alexander, Christopher Kane and blogger Susie Lau that Riis deserved a bigger platform.
Ann-Sofie Johansson, H&Ms head of design, said: Stine Riis impressed us all with the maturity and modernity of her work. Her collection was so complete, and so well finished. It was such a sophisticated show, and such an exciting occasion.
