Artist-turned-designer Simeon Farrar found fame with his graphic-print tops, dresses and accessories, but it was his 'Kate Mouse' T-shirt that made him an instant favorite with It girls and editors alike. Following the devastating earthquakes in Japan earlier this year, Farrar has relaunched this iconic design to raise money for those affected - and, with the help of NET-A-PORTER, 50% of the profits will go towards the Japanese Red Cross charity appeal.
